The main characteristic of evaluation is that a coal face is a evaluation cell.The aticle tells of fuzzy evaluation on coal seam geological conditions in Jisan Mine.2 CONDITIONS OF SEAM AND GEOLOGYThere are three sections that are exploited in Jisan Mine,i.e. north section﹑east section﹑west section,they belongs to Sanxia coal seam. Sanxia coal seam is at the bottom of Shanxizu,mean thickness of coal seam is 5.26 metres,from east to west in Mine,thickness of coal seam reduce from 5 metres to 3.5 metre. Rock character of roof is sandrock or siltite,rock character of bottom is siltite or thin sandrock. There are many faults in Jisan Mine,there are fourteen faults that their drops are bigger thantwenty metres,and there are many smaller faults. Based on the coal seam geological conditions,strike longwall mining method in fully mechanized coalface is adopted.3 FACTORS AND INDEX OF EV ALUATION3.1 STRUCTURE OF EV ALUATION FACTORSAccording to the principle of system,feasibility and simplicity,based on coal seam geological characteristic ,the structure of evaluation factors is figure 3.1.It consists of seven compound factors and eleven smaller factors,these factors are quantified by fault density q1﹑fault length exponent q2﹑fault fall exponent q3﹑variation of coal seam and band coefficient γ﹑seam thickness m﹑seam angle α﹑seam hardness R﹑immediate roof hardnessσ﹑ratio of immediate roof and seam mining thickness N﹑false roof thickness h0﹑immediate bottom hardness q c﹑coal face length l and coal face advance length s.Figure 3-1 structure of evaluation factors of coal face3.2 INDEX SYSTEM OF EV ALUATIONExplanation of eleven smaller evaluation factors is as follows:(1)fault effect:describing fault effect on mining needs three index,faultdensity-fault number in unit area;fault length-sum of fault length in unit area;fault fall exponent-ratio of fault fall and seam thickness.(2) variation of coal seam and band coefficient : ratio of seam thickness sample standard deviation and seam thickness mean. (3) Seam thickness : seam sample thickness mean. (4) Seam angle : seam sample angle mean.(5) Seam hardness : seam compression strength.(6) Immediate roof hardness : immediate roof compression strength. (7) Main roof holding power :(8) False roof effect : false roof thickness.(9) Immediate bottom hardness : immediate roof compression strength. (10) C oal face length (11) C oal face advance3.3 MEMBERSHIP FUNCTIONS OF EV ALUATION FACTORSThe membership function of evaluation factor is the quantitative description on fuzzy relationship between the change of a geological factor and the mining effect. Membership function is the foundation to build a fuzzy evaluation model.Adopting statistic analogism method , method of undetermined coefficients and heterogeneous fuzzy statistic method , membership functions are obtained as follows : (1)membership function of fault effectμa =2/ (1+exp (0.0018+0.042×q 1+0.064×q 2+0.00071×q 3))(2)membership function of variation of coal seam and band coefficient(3)membership function of seam thickness⎪⎩⎪⎨⎧><≤+⨯-<=5.01.05.02.06.132.00.1)(000000h h h h h h μ(4)membership function of seam angle⎪⎩⎪⎨⎧≥<≤<=3N 1.03N 0.31.8 + N) Exp(-0.29 1.9-0.3N 0.05(N)μN(5)membership function of seam hardness0.17.2()0.51ln 0.917.2421.042c c R c c c c R R R R R μ<⎧⎪=⨯-≤≤⎨⎪>⎩⎪⎪⎩⎪⎪⎨⎧<≤>≥-<≤+⨯+⨯<=-8040403002.08.10.1301671.0012.01069.1ln(164.0)(24σσσσσσσσμσ(6)membership function of immediate roof hardness100010001001000.17.2)ln(5.00)(≥≤<≤⎪⎩⎪⎨⎧-=s s s s s S μ(7)main roof holding power⎪⎪⎪⎩⎪⎪⎪⎨⎧<≤+-<≤+-<≤+-<≤<≤=5036528.10286.036180.101389.018125.104167.01260.1631667.0)(R R R R R R R R R R R μ(8)false roof effect⎩⎨⎧≥<≤⨯-=25.0025.00)(21)(5.0γγγγμγ(9)immediate bottom hardness⎪⎪⎪⎪⎩⎪⎪⎪⎪⎨⎧≥<≤-⨯<≤+⨯<≤-⨯<≤-⨯<≤-⨯=1500.1150130275.00085.0130100483.0000667.0100805.00125.080607.0015.060401.0005.0)(l l l l l l l l l l l l L μ (10)coal face length⎪⎪⎪⎪⎪⎩⎪⎪⎪⎪⎪⎨⎧≥<≤<≤+⨯-<≤<≤-⨯<≤+⨯<≤-⨯<≤+⨯=0.50.10.55.470.05.45.370.12.05.38.20.18.25.252.19.05.20.243.012.00.24.123.045.04.10.105.025.0)(m m m m m m m m m m m m m m m μ (11)coal advance length⎪⎪⎪⎪⎪⎩⎪⎪⎪⎪⎪⎨⎧≥<≤<≤+⨯-<≤<≤-⨯<≤+⨯<≤-⨯<≤+⨯=0.50.10.55.470.05.45.370.12.05.38.20.18.25.252.19.05.20.243.012.00.24.123.045.04.10.105.025.0)(m m m m m m m m m m m m m m m μ 3.4 WEIGHTS OF EV ALUATION FACTORSWeight of evaluation factors is a quantity that show relative importance of per factor in system ,it is the key to unify systemic structure and function.Coam seam geological evaluation of coal face ascertains weights of evaluation factors by AHP.AHP is a easy method to quantify the quanlitative event.Appliacation of AHP needs five steps :building hierarchical model 、constructing judgement matrix 、single hierarchy collation and consistency check 、total hierarchy collation 、consistency check of total hierarchy collation.Comfirmatiom of judgement matrix is the key to use AHP ,value of judgement matrix is the quantitative description on relative importance of per factor ,the valves are one to nine and their reciprocals.Table1 shows the value ,Table2 to 4 show judgement matrix ,Table5 shows weights of evaluation factors.Figure 3B6~C judgement matrix3.5 FUZZY EV ALUATION MODELCoal seam geological conditions are multilayered evaluated by fuzzy evaluation model,fuzzy evaluation model images single factor evaluation value to total evaluation value by certain algorithm,whether propertis of evaluation sample is bad orgood are assured by total evaluation valve ,in order to comprehesively consider effect degree of per factor ,weighted avarage evaluation model is used ,the model :∑==⋅=ni ij i j m j r W b 1.....,1,2, In fomula :b j ——evaluation valve ; W i ——weight matrix 。

原文:DEVELOPING OF TRANS-CENTURY MINING SUBJECTWITH NEW TECHNOLOGY AND NEW THEORYAbstract:Mining subject needs further development and towards which the development would being the problems concerned over all along and to be succeeded with the public good enough attention to discussions to reach an identify of views admittedly. The emergence in succession of new-and-high techs in the mid-and late twentieth century is perhaps the most fascinating and epoch-marking event that has given to all the subjects certain but different degrees of impacts to become more closely interrelative and interdepartmental each other and feature specifically from that of the past for their entirely new conceptions in the result of formulating many new theories,new technologies and new subjects that mining subject is inevitably and unexceptionally the one inclusive. The acuter gives in this paper his opinion regarding the problem of the development of mining subject proving with many convincible facts and most informative new idea,Key words: mining subject; mineral industry; mineral economics; new-and-high tech.1 The Importance of Mining Industry in the National EconomyToday, it has been paid unprecedented attention to the development of technology worldwide.The advance of space engineering,information engineering,biological engineering and marine engineering,the discovery and the research and development of the new energy and new materials increasingly change every aspect of human life both at present and in the future.The words "Science and Technology being the First Production Force" has fatherly and penetratingly pointed out the important role of new technology in the course of national economy construction.In the competition of several big countries in the world striving for the exploration of outer space,one should not forget the essential fact that there are more than five billion people living on the earth. To assure the survival of mankind on the earth,four essential requirements should be considerably fulfilled,namely,the nutrients,materials,fuels and the environment. The nutrients mainly are air,water,forests,grains and miscellaneous plants,all of which are acquired from the nature. The materials refer to iron,ferrous metals,rare metals,precious metals,chemical raw materials and building materials. The fuels cover coal,petroleum,natural gas ,oil shale,uranium,thorium and other radioactive elements. These also occur in nature. The last one is the ecological environment depending on which mankind lives. In the above three essential substances,the materials and fuels are through mining engineering extract from bining industry is a conventional industry, however,with the advance of the new technologies and the introduction of them into mining industry which will be reduced of itself final1y- a technology-intensive industry. The emergence of highly mechanized and automated mines and robot-operated manless working face marks the renewal and substitution of technologies of mining industry and proves the fact that mining industry.However,is conventional industry, but not sunset industry. As long as mankind live on the earth,mining industry will last forever and never decline and fall,instead,as man's living demands increases,the output of fuels and raw materials will be increased by a big marg and mineral industry will still gain a much greater development.2The Object of Study of the Mining Subject2. 1 The Tasks and the Special Features of 1liining SubjectHistorically and the Special Features of 1liining Subject the development of mining subject has its own course of change and development both at home and abroad. Since mining industry is closely related with geology, metallurgical and energy industry consequently in the subject relationships,they are interrelative and interdepartmental each other. As mining subject branch of science dealing with the extraction and utilization of minerals and the resources from inside the earth,on the sake of the complexity and multiplicity of the rock mass and mineral resources of great nature which makes the basic theories of mining subject being more complicated than that of any other engineering subject. Especially in the following aspects featured: the objects of mining subjects are the ore bodies occurred in nature that they differ each other in structure,quality,and property.3Five Urgent Requirements on the Tendency towards the Trans-century Development of Modern Mining Subjects3. 1 Renewing the Knowledge of Strata 11ZechanicsAbove all rock and or ore properties are the prerequisites of the subjects of the study of mining engineering regardless of whether it is excavation,comminuting or strata ,stability strata mechanics is required to make the study along two aspects:(1)From the micro-study to the macro-study(2) The study of the contradictions between rock-breaking and rock stability in the course of mining and excavating. Therefore it is a very broad field of academic studyComparing with common solid materials,rocks are featured structurally for their non-homo.3.2 AnewKnowledgeofMiningEngineeringSystem-the"hian-Nature-Rfachine" Systern ,System engineering had found in recent years very rapid development,and wide applications m mining engineering. Been modeled after the "man-machine’s Generally, mining systems engineering considerably studies had system model used in aerospace engineering and other departments of en Bering. In recent years,Prof. Fettwice of the Montan University of Austria and the author of this paper both had put forth the opinion that the objects of mining engineerm8 Machine are ore bodies and rock strata, the activities of mining engineering are those played with by the man in getting the knowledge of the environment underground.3.3 Reforming the Conventional Mining Technologies and Industries withModern New technologiesThe major policy of China of reforming the conventional industries with new-and-high techsof great importance and no doubt to its conventional industries.The essential features of new-and-high techs are highly technology-intensive.Just as discussed in the beginning of this paper,speaking with respect to the reforming of mining engineering and coal industry with new-and-high techs,it is essential to introduce merely those ones which enable to make these two industries swiftly commercialized. Since mine is concerned with the natural surroundgas of ground,the newtechs,however,as those used in aerospace engineering in the care for "going up to sky" when used for 0gettingdown intothe earthin mining engineering practices evidently are needed to make completely different modalities. In 1080s,Berlin Poly }ethnic university had applied optic fiber telecommunication technology- in underground mining,giving rise to abundant interference problems of earth magnetism,electricity and light wave, and the insulation of strata to the conduction electronic waves. The BPM man had the problems s finally tailed,however,through a long time of research work. Therefore,to have the minerals industries well prepared technically for the 21st century,to paying great attention the following fields of study are required3.3.4Making the study of market-economy mineral economics theoriesFor a long time that the mineral economics theory in China had been given distinct features of planning economy,while in the theory itself,mineral resources were not recognized ascommodities and had no prices. Consequently,even though the mineral products had pricesbut were distorted ones making all national mining enterprises non-profitable and to exist depending on governmental policy-subsidization. Now the country, however,has changed intosocialist market economy, most mineral enterprises radically cannot accommodate themselvesto this new situation,in particular,from the point of view of "Enriching the peasants" policyto put forward to the exploitation of mineral resources,the near-term policy of the so-called“wherever there’ water,flow it fast",which had made the mineral industry from the repeated view-point of and the enriching the Pleasants policy, has caused the price deficit due to lowselling-price of minerals into even worse situation of disorder,no-restraint and anarchy ofscrambling for extracting the mineral resources putting the mineral industries in a tight spot unabling to feed themselves. Under this circumstance,the importance of undertaking the softscience research right now becomes more conspicuous to the mineral industries than ever before. One can predict that had the theoretical study of mineral economics theory been made ,portent break troughs,that it would radically change the face of our mineral industries.3.5 Relationship between Mineral Engineering and Natural EcologyMining engineering is the removal of rocks and minerals to the surface throughexcavations from underground deep in the earth or from the ground surface leaving the excavated space so formed. Every turn meters Surface every year subsidence in China. of the commodity flow of mining products reaches billion cubic Obviously it has caused many negative effects,for example:(1)uses of waste rock which results in the damages of farming lands and houses;(2) Large volrefuse and tailings occupy large area of land; and (3) Coal and oil burning products give off waste materials,such as exhaust gas,waste liquids,and solids and pollute the environment. In China,80 percent of 1. 1 billion tons of coalburned as fuel,from which,dust,sulpher and the of NO2and CO2 and the effective less heating effect seriously constitutes a menace to the ecological environment of China and the neighboring countries.4Suggestions opment of to the Science and Technology Circles of the Nation for the Develop-the Mining Subject4.1 An Unguent AppealNo doubt the "flying up into the sky" technology is the one most advanced,however,thegetting down into the earth" technology in mining engineering is no less complex,and even more difficult to pin down. It is no wonder that people consider that mineral engineering beingmuch simpler and pay less attention for lack of the knowledge of the resulting in the low rate ofmineral recovery and low rate of mineral extracting. For this country, but to spend a greatmany of valuable hard currency to import those actually need not to import raw materials andelse,naturally this is not favorable to the development of national economy. Hoping the science and technology circles,in particular their leading departments,renewing their recognitions to this awkward situation,and give necessary support to the urgently-needed topics of research studies of the mineral industries.4.2 National Resource PolicyNational resource policy concerns the future for many generations.Hoping the government population institutions relevant learn Iron the lesson of the past population policy,to take measures as early as possible to have the print up of mineral resources centralized.4.3 Mineral Investment PolicyThe investment policy and the set up of mineral industries should be dire; iron: tm common industries to assure in the long run the first energy supply 1vit} necessary and appropriate support.4.4 Make Ready the SuccessorsTo make ready the successors for the mineral industries and the development of the mining subjects,suggesting to give preferential treatment to the university.Admissionssystem and the recruitment of mineral workersand set mineral science.Foundation as an important subject independent from the foundations of those.Basic science in the natural science foundation.The aim of writing this paper is to hone that in the tonguingA of this centuryminim subject in China will have a new prosperous development with the of new technology to theory under the guidance of the national science policy.译文:新技术和新理论的采矿业跨世纪发展摘要:煤炭产业需要更长远的发展,对工作中所讨论的热点在工业中出现新的理论和高科技成功使用在二十世纪末是最美好的,作为被关心的问题需要较快一步的发展,在20世纪中后期产生的新型、高速的新技术是最有吸引力和标志性的,即使在所有行业中不同的冲击变得起来越相关以及部门间彼此合作并明确地叙述许多新的理论,煤炭行业的新科技和新理论是不可避免的,并且包括一切的不可能性。

知识经济将对矿业科技的发展发挥重要作用。
文中详细论述了地下金属矿采矿科学技术的发展趋势,即高效率采矿,无废害采矿,连续采矿,深部采矿,无人采矿。
关键词:知识经济;地下金属矿山;采矿科学技术;发展趋势1 引言世界进入工业经济时代已有200多年的历史。
21世纪,世界将进入全球化的知识经济时代。
何谓知识经济?20世纪80年代以来,许多学者对信息技术革命所产生的巨大影响,进行了大量研究和预测,他们从不同的角度去思考和概括,先后提出了“后工业经济”、“高技术经济”、“信息经济”、“数字经济”、“网络经济”等新概念,直到1996年“经济与发展组织”将这种新型经济称之为“以知识为基础的经济”,从此,知识经济的概念被越来越多的人所接受。
所谓知识经济是建立在知识和信息的生产、传播与应用基础上的经济。
它的基本内涵是:以智力资源为依托、以高技术产业为支柱、以知识创新为动力、以创造教育为本源的一种新的经济形态。
21世纪,我们的矿业将处于什么地位呢?人类不可能脱离物质需要而生存,即使在知识经济时代,矿业仍然是人类不可缺少的物质来源。
根据有关资料,1997年,采矿工业为全世界提供了210亿t原材料,总产值高达2万亿美元,占全世界总产值28.2万亿美元的7.1%。
因此,采矿工业过去是、现在是、将来仍然是全球经济持续发展的基础。
近十多年来,现代高新技术的发展,给世界矿业带来了机遇,如矿山设备大型化、智能化,以及计算机技术和信息技术,全球卫星定位系统,生物溶浸技术等等在矿业领域的应用,已成为矿业科技发展的源泉和动力。
21世纪的矿业目标———广泛吸收各学科的高新技术,开拓先进的、非传统的采矿技术,创造更高效率、更低成本、最少环境污染和较好安全条件的采矿模式,为人类提供巨大的物质财富,以满足不断增长的世界人口对生活质量的需求,促进社会经济的持续发展。

ROOM-AND-PILLAR METHOD OF OPEN-STOPE MINING空场采矿法中的房柱采矿法Chapter 1.A Classification of the Room-and-Pillar Method of Open-Stope Mining第一部分,空场采矿的房柱法的分类OPEN STOPING空场采矿法An open stope is an underground cavity from which the initial ore has been mined. Caving of the opening is prevented (at least temporarily) by support from the unmined ore or waste left in the stope,in the form of pillars,and the stope walls (also called ribs or abutments). In addition to this primary may also be required using rockbolts , reinforcing rods, split pipes ,or shotcrete to stabilize the rock surface immediately adjacent to the opening. The secondary reinforcement procedure does not preclude the method classified as open stoping.露天采场台阶是开采了地下矿石后形成的地下洞室。

2013 届毕业文献翻译题目文献翻译专业班级采矿工程学号 09010901xx学生姓名刘xx指导教师张电吉指导教师职称教授学院名称环境与城市建设学院完成日期: 2013 年 6 月日Room and pillar Mining MethodsBullock(1982a),quoting previous data, showed that room and pillar mining together with stope and pillar mining accounted for most of the underground mining in the United States. He estimated that 60% of noncoal minerals (about 80 million tons or 70 Mt) and 90% of coal ( about 290 million tons or 260 Mt) were obtained by room and pillar methods, and it is unlikely that things are radically different today. The method is cheap, highly productive, easily mechanized, and relatively simple to design.The room and pillar mining method (Fig.5. 2) is a type of open stoping used in near horizontal deposits in reasonably competent rock, where the roof is supported primarily by pillars. Ore is extracted from rectangular shaped rooms or entries in the ore body, leaving parts of the ore between the entries as pillars to support the hanging wall or roof. The pillars are arranged in a regular pattern, or grid, to simplify planning and operation. They can be any shape but are usually square or rectangular. The dimensions of the rooms and pillars depend on many design factors. These include the stability of the hanging wall and the strength of the ore in the pillars, the thickness of the deposit, and the depth of mining. The objective of design is to extract the maximum amount of ore that is compatible with safe working conditions. The ore left in the pillars is usually regarded as irrecoverable or recoverable only with backfill in noncoal mines.applications of pillar mining have been discussed by Hamrin ( 1982) and Hittman( Anon. . 1976) among others. Suitable conditions include ore that are horizontal or have a dip of less than 30°. A major requirement is that the hanging wall is relatively competent over a short period of time, or is capable of support by rock bolts that are used extensively in room and pillar mining. The method:! is particularly suited to bedded deposits of moderate thickness (2 to 6 m) such as coal-the main application一salt, potash, and limestone.Figure.5.2Room and pillar mining method.1, Methods of Room and Pillar MiningRoom and pillar mining takes place in sections or panels, which are usually rectangular and regular in plan. In hard rock mining of horizontal ore bodies, the method is very similar to open stoping. In many cases, ore grade control may be the primary requirement in mine design, and ground control and ventilation secondary considerations. This may lead to an ad hoc room and pillar design with irregular- , nonrecoverable pillars of low-grade ore.Hard-rock room and pillar mining is a effectively method of open stoping (stope and pillar mining) at a low angle to the horizontal, excavating rooms and leaving supporting pillars.Where mineral values vary, the method is similar to the old “gophering" method of mining where random excavations followed highly mineralized zones. Where mineral values are consistent, the mine layout can be regular. The method differs from most hard-rock mining methods in that gravity flow is limited, and ore must be loaded in the excavation where it has been blasted and transported from that point. In large operations this involves trucks and loaders or load — haul — dumps ( LHDs).There are various methods of room and pillar stoping. The most common are full-face slicing breast stoping and multiple slicing or bench and breast stoping. In the former, the rooms are opened to their full vertical height with no mineral or economic value left in the roof or the floor. probably the reasonable safe limit for full-face slicing is 8 to 10 m depending on drilling and support equipment, and beyond this, multiple slicing is used.2. Production CycleFor hard-rock ore bodies ,the basic cycle is similar to hard-rock tunneling four main elements, (1)mark out and drill blast holes , usually in a wedge pattern , (2) ,and ventilate to remove blast fumes ,(3) introduce mucker and muck and load,and ④scale the face and walls and bolt the roof where necessary. There is considerable complexity in the interaction among these elements that make up a basic critical path. In order to estimate the cycle time, it is necessary to determine unit loading and drilling rates and task times for these elements and also to estimate how subsidiary elements and tasks such as haulage and ventilation takeup may impinge upon the critical path in a badly organized mine.3.Panel DevelopmentA panel layout for a typical room and pillar mine in a noncoal mine is illustrated as follows :The excavation height is about 4.5m,and the normal sloping practice is to drive a single development drift about 10. 5 m wide a distance of about four or five rooms into the ore body. This will serve as the main haulage drift. Pillars are then marked out on the drift walls and rooms driven between them.To drill and blast the initial drive when the only exposed or free face is the drive face, some form of cut pattern is used. This is known as the “ face round or “ swing and in a 4. 5 by 10.5 m face will comprise 60 to 70 holes of about 8 mm to a depth at 3 to 3. 6 m. If more than one face is exposed,a group of holes may be drilled at a low angle to the free face in what is known as a " slab round or slabbing or “slashing”. This requires less explosive and less drilling than a single face. the most common form of face round is a wedge or V, cut although bum cuts can also beDrilling is carried out with jumbo-mounted hydraulic drills ;loading is usually by gathering arm loader, although in modern mines, trackless LHD vehicles are used to the load to a transfer raise where it is reloaded into trucks or conveyors.房柱法Bullock在1982年提出房柱法,它指在矿房与矿柱里回采矿物,在美国大多数地下开采应用柱式开采。

关于采煤煤炭方面的外文翻译、中英文翻译、外文文献翻译附录AProfile : Coal is China's main energy in the country's total primary energy accounted for 76% and above. Most coal strata formed and restore the environment, coal mining in the oxidizing environment, Flow iron ore mine with water and exposed to the air, after a series of oxidation and hydrolysis, so that water acidic. formation of acidic mine water. On groundwater and other environmental facilities, and so on have a certain impact on the environment and destruction. In this paper, the acidic mine water hazards, and the formation of acid mine water in the prevention and treatment of simple exposition. Keywords : mining activities acidic mine water prevention and correction of the environmental impact of coal a foreword is China's main energy, China accounted for one-time energy above 76%, will conduct extensive mining. Mining process undermined the seam office environment, the reduction of its original environment into oxidizing environment. Coal generally contain about 0.3% ~ 5% of sulfur, mainly in the form of pyrite, sulfur coal accounts for about 2 / 3. Coal mining in the oxidizing environment, flow and iron ore mine water and exposed to the air, after a series of oxidation, hydrolysis reaction to produce sulfuric acid and iron hydroxide, acidic water showed that the production of acid mine water. PH value lower than the six said acidic mine water mine water. Acid mine water in parts of the country in the South in particular coal mine were more widely. South China coal mine water in general pH 2.5 ~ 5.8, sometimes 2.0. Low pH causes and coal of high sulfur closely related. Acid mine water to the formation of ground water have caused serious pollution, whilealso corrosion pipes, pumps, Underground rail, and other equipment and the concrete wall, but also serious pollution of surface water and soil, river shrimp pictures, soil compaction, crops wither and affect human health. An acidic mine water hazards mine water pH is below 6 is acidic, metal equipment for a certain corrosive; pH is less than 4 has strong corrosive influence on the safety in production and the ecological environment in mining areas serious harm. Specifically, there are the following : a "corrosive underground rail, rope and other coal transport equipment. If rail, rope by the pH value "4 acidic mine water erosion, 10 days to Jishitian its intensity will be greatly reduced, Transport can cause accidents; 2 "prospecting low pH goaf water, Quality Control iron pipes and the gate under the flow erosion corrosion soon.3 "acidic mine water SO42-content high, and cement production of certain components interact water sulfate crystallization. These salts are generated when the expansion. After determination of when SO42-generation CaSO4 ? 2H2O, the volume increased by 100%; Formation MgSO4.7H2O, v olume increased 430%; Volume increases, the structure of concrete structures.4 "acidic mine water or environmental pollution. Acid mine water is discharged into rivers, the quality of pH less than 4:00, would fish died; Acidic mine water into the soil, damage granular soil structure, soil compaction, arid crop yields fall, affecting workers and peasants; Acid mine water humans can not drink that long-term exposure, people will limbs broken, eyes suffering, enter the body through the food chain. affect human health. 2 acidic mine water and the reasons are mostly coal strata formed in the reduction environment, containing pyrite (FeS2) formed inthe seam-reduction environment. Coal generally contain about 0.3% ~ 5% of sulfur, mainly in the form of pyrite, sulfur coal accounts for about 2 / 3. Coal mining in the oxidizing environment, flow and iron ore mine water and exposed to the air, after a series of oxidation, hydrolysis reaction to produce sulfuric acid and iron hydroxide, acidic water showed that the production of acid mine water. Acidic mine water that is the main reason for forming the main chemical reaction as follows : a "pyrite oxidation and free sulfate ferrous sulfate : 2FeS2 O2 +7 +2 +2 H2O 2H2SO4 FeSO4 2 "ferrous sulfate in the role of oxygen free Under into sulfate : 4FeSO4 +2 Cp'2Fe2 H2SO4 + O2 (SO4) 3 +2 H2O 3 "in the mine water The oxidation of ferrous sulfate, sometimes not necessarily need to sulfate : 12FeS2 O2 +6 +3 H2O 4Fe2 (SO4) 3 +4 Fe (OH) 3 4 "mine water Sulfate is further dissolved sulfide minerals in various roles : Fe2 (SO4) 3 + MS + H2O + / 2 + O2 M SO4 H2SO FeSO4 +5 " ferric sulfate in the water occurred weak acid hydrolysis sulfate produced free : Fe2 (SO4) 3 +6 H2O two Fe (OH) 3 +3 H2SO4 6 "deep in the mine containing H2S high, the reduction of conditions, the ferrous sulfate-rich mine water can produce sulfuric acid free : 2FeSO4 +5 FeS2 H2S 2 +3 +4 S + H2O H2SO4 acidic mine water in addition to the nature and sulfur coal on the other, with the mine water discharge, confined state, ventilation conditions, seam inclination, mining depth and size, water flow channels and other geological conditions and mining methods. Mine Inflow stability, stability of acidic water; Confined poor, good air circulation, the more acidic the water, Fe3 + ion content more; Instead, the acid is weak, the more Fe2 + ion; more deep mining of coal with a sulfur content higher; The larger the area of mining, water flowsthrough the channel longer, oxidation, hydrolysis reactions from the more full, the water more acidic strong, If not weak. 3 acidic mine water prevention and control ? a three acidic mine water under the Prevention of acidic mine water formation conditions and causes from source reduction, reductions, reduced when three aspects to prevent or mitigate damage. 1 "by the source : the seizure election made use of mineral acid, being the case. The main coal-bed mineral create acid when in a mixture of coal pyrite nodules and coal with a sulfur content itself. Coal mining rate is low and residual coal pillars or floating coal lost, abandoned pyrite nodules underground goaf, in which long-term water immersion, Acidic water produced is a major source. Face to reduce the loss of float coal, theuse of positive seized election pyrite nodules, can reduce the production of acidic water substances. Intercept surface water, reduce infiltration. For example, the filling of waste, control of roof to prevent collapse fissures along the surface water immersion goaf. In Underground, particularly old or abandoned wells closed shaft, the mine water discharge appropriate antibacterial agent, kill or inhibit microbial activity, or reduce the microbial mine water quantity. By reducing microbial sulfide on the effective role and to control the generation of acid mine drainage purposes. 2 "reduced discharge : the establishment of specialized drainage system, centralized emission acidic water, and storing up on the surface, it evaporated, condensed, then to be addressed to remove pollution. 3 "to reduce emissions of acid water in time : to reduce the underground mine water in the length of stay, in a certain extent, to reduce the microbial coal oxidation of sulphides, thus helping to reduce acid mine water. Containing pyrite, sulfur, surface water leakage conditions for agood shallow seam, or have formed strong acidic water stagnant water in the old cellar, the pioneering layout to weigh the pros and arrangements, not early in the mine prospecting or mining, leaving the end of mine water treatment avoid long-term emissions acidic water. ? 2 3 acidic mine water treatment in certain geological conditions, Acidic water with calcium sulfate rock or other basic mineral occurrence and the reaction decreases acidity. Neutralizer with caustic soda used for less, less sludge is generated, but the total water hardness is often high, while reducing the acidity of the water. However, an increase in the hardness, and the high cost is no longer. Currently, treatment for a neutralizer to the milk of lime, limestone for the neutralizer and limestone -- lime, microbiological method and wetlands treatment. Neutralizer milk of lime treatment method applicable to the handling of a strong acid, Inflow smaller mine water; Limestone -- lime applied to various acidic mine water. especially when acidic mine water Fe2 + ions more applicable, but also can reduce the amount of lime; microbiological method applied when the basic tenets of iron oxide bacterial oxidation than iron, bacteria from the aquatic environment intake of iron, then to form ferric hydroxide precipitation-iron in their mucus secretions, Acidic water at the low iron into high-iron precipitates out and then reuse limestone and free sulfuric acid, can reduce investment, reduce sediment. Wetlands Act also known as shallow marshes, this method is low cost and easy operation, high efficiency, specific methods not go into details here. Conclusions Most coal strata formed and restore the environment, coal mining in the oxidizing environment, Flow iron ore mine with water and exposed to the air, after a series of oxidation and hydrolysis, so that water acidic. formation of acidicmine water. On groundwater and other environmental facilities, and so on have a certain impact on the environment and destruction, Meanwhile harmful to human health caused some influence. Based on the acidic mine water cause analysis, and to take certain preventive and treatment measures, reduce acid mine water pollution in the groundwater, environmental and other facilities and the damage caused to human health effects.

外文原文:Adopt the crest of the coal work noodles plank managementproblem studyCrest the plank management is the point that adopts a safe management of the coal work noodles.Statistics according to the data, crest the plank trouble has 60% of the coal mine trouble about, adopting the trouble of the coal work noodles and having a crest 70% of the plank trouble above.Therefore, we have to strengthen a plank management, reducing to adopt the coal work noodles crest the occurrence of the plank trouble.1,the definition of the crest,scaleboard and it categorizeEndow with the existence coal seam on of the close by rock strata be called a plank, endow with the existence coal seam under of the close by rock strata be called scaleboard.Crest the rock,strength of the scaleboard and absorb water sex and digging to work the management of the noodles contain direct relation, they is certain crest the plank protect a way and choose to adopt the empty area processing method of main basis.1.1 planks categorizeAccording to rock,thickness and return to adopt process to fall in the 垮of difficult easy degree, crest the plank is divided into the false crest,direct crest and old crest.According to direct crest sport to adopt a field to the influence for press, the direct crest is divided into broken up,unsteady,medium etc. stability,stability,strong and tough crest plank etc. is five.According to old crest the sport Be work mineral inside the noodles press to present degree and to work safe threat of noodles of size, the old crest is is divided in to press very and severely, press mightiness, press to compare obviously, don't obviously press etc. is four.1.2 scaleboards categorizeAccording to the opposite position relation of the rock strata and the coal seam, the scaleboard is divided into direct bottom with the old bottom.Locate coal seam directly under of the rock strata be called direct bottom;locate the direct bottom or coal seam under of the rock strata be called old bottom.The coal seam crest the scaleboard type expects the influence of the geology structure sport after be subjected to the deposition environment and, its growth in different region degree dissimilarity, the coal seam possibility for have isn't whole.2,crest that need to be control plank classification and adopt the processing way of the empty areaAccording to different crest the plank type and property, choose to pay to protect a way and adopt the empty area processing method differently, is a plank management of basic principle.2.1 crest needed to pull to make plank classificationPress a knothole rock strata strength, the crest plank that needs to be control can is divided into: general crest the plank,slowness descend to sink a plank and is whole fall the crest of the cave in the danger plank etc..2.2 work noodles adopt the processing method of the empty areaThe processing method that adopts empty area mainly has: all 垮s fall a method,partial full to fill a method,the coal pillar to prop up a method to alleviate to descend to sink a method slowly etc..3,crest the plank pressure present a characteristic3.1 top the cover rock strata of the sport regulation and the work in front pay to accept pressure to distribute behindDuring the period of mine, adopt empty area above of the rock strata will take place ambulation, according to crest the plank change mind condition, taking the cranny rock strata in up the cover rock strata follow the work noodles to push forward the direction demarcation as three areas: the coal wall prop up the influence area,leave layer area and re- press solid area.The noodles opens to slice an eye to go to push forward forward in the process from the work, break original should the equilibrium of the dint field, cause should the dint re- distribute.Be adopting the coal work noodles to become to pay to accept pressure in front and back, it concretely distributes shape to have something to do with adopting the empty area processing method.3.2 first times to press to press a main manifestation with the periodFirst time to press a main manifestation:BE a plank"by oneself the vield song" range enlargement;the coal wall transform and fall to fall(the slice help);pay to protect to drill bottom etc..First time to press to want to keep on more and suddenly and generally for 2-3 days.Period to press a main manifestation:Main manifestation BE:crest the plank descend to sink nasty play increment of speed, crest the plank descend to sink quantity to become big;pay what pillar be subjected to load widespread increment;adopt empty area to hang a crest;pay pillar to make a noise;cause the coal wall slice to help,pay pillar to damage,crest plank occurrence the step descend to sink etc..If pay the pillar parameter choice to be unsuited to a proper or single body to pay the pillar stability worse, may cause the partial crest or crest plank follow the work noodles to slice to fall etc..4,crest the plank choice for protectThe work noodles the function for protect decelerate a plank to descend to sink, supporting to control a crest to be apart from the knothole integrity inside the crest,

The emergence in succession of new-and-high techs in the mid-and late twentieth century is perhaps the most fascinating and epoch-marking event that has given to all the subjects certain but different degrees of impacts to become more closely interrelative and interdepartmental each other and feature specifically from that of the past for their entirely new conceptions in the result of formulating many new theories,new technologies and new subjects that mining subject is inevitably and unexceptionally the one inclusive. The acuter gives in this paper his opinion regarding the problem of the development of mining subject proving with many convincible facts and most informative new idea,Key words: mining subject; mineral industry; mineral economics; new-and-high tech.1 The Importance of Mining Industry in the National EconomyToday,it has been paid unprecedented attention to the development of technology worldwide. The advance of space engineering,information engineering,biological engineering and marine engineering,the discovery and the research and development of the new energy and new materials increasingly change every aspect of human life both at present and in the future. The words "Science and Technology being the First Production Force" has fatherly and penetratingly pointed out the important role of new technology in the course of national economy construction.In the competition of several big countries in the world striving for the exploration of outer space,one should not forget the essential fact that there are more than five billion people living on the earth. To assure the survival of mankind on the earth,four essential requirements should be considerably fulfilled,namely,the nutrients,materials,fuels and the environment. The nutrients mainly are air,water,forests,grains and miscellaneous plants,all of which are acquired from the nature. The materials refer to iron,ferrous metals,rare metals,precious metals,chemical raw materials and building materials. The fuels cover coal,petroleum,natural gas ,oil shale,uranium,thorium and other radioactive elements. These also occur in nature. The last one is the ecological environment depending on which mankind lives. In the above threeessential substances,the materials and fuels are through mining engineering extract from bining industry is a conventional industry,however,with the advance of the new technologies and the introduction of them into mining industry which will be reduced of itself final1y- a technology-intensive industry. The emergence of highly mechanized and automated mines and robot-operated manless working face marks the renewal and substitution of technologies of mining industry and proves the fact that mining industry. However,is conventional industry,but not sunset industry. As long as mankind live on the earth,mining industry will last forever and never decline and fall,instead,as man's living demands increases,the output of fuels and raw materials will be increased by a big marg and mineral industry will still gain a much greater development.2The Object of Study of the Mining Subject2. 1 The Tasks and the Special Features of 1liining SubjectHistorically and the Special Features of 1liining Subject the development of mining subject has its own course of change and development both at home and abroad. Since mining industry is closely related with geology,metallurgical and energy industry consequently in the subject relationships,they are interrelative and interdepartmental each other. As mining subject branch of science dealing with the extraction and utilization of minerals and the resources from inside the earth,on the sake of the complexity and multiplicity of the rock mass and mineral resources of great nature which makes the basic theories of mining subject being more complicated than that of any other engineering subject. Especially in the following aspects featured: the objects of mining subjects are the ore bodies occurred in nature that they differ each other in structure,quality,and property.3Five Urgent Requirements on the Tendency towards the Trans-century Development of Modern Mining Subjects3. 1 Renewing the Knowledge of Strata 11ZechanicsAbove all rock and or ore properties are the prerequisites of the subjects of the study of mining engineering regardless of whether it is excavation,comminuting or strata ,stability strata mechanics is required to make the study along two aspects:(1)From the micro-study to the macro-study(2) The study of the contradictions between rock-breaking and rock stability in the course of mining and excavating. Therefore it is a very broad field of academic study Comparing with common solid materials,rocks are featured structurally for their non-homo.3.2 Anew Knowledge of Mining EngineeringSystem-the"hian-Nature-Rfachine" Systern ,System engineering had found in recent years very rapid development,and wide applications m mining engineering. Been modeled after the "man-machine’s Generally,mining systems engineering considerably studies had system model used in aerospace engineering and other departments of en Bering. In recent years,Prof. Fettwice of the Montan University of Austria and the author of this paper both had put forth the opinion that the objects of mining engineerm8 Machine are ore bodies and rock strata,the activities of mining engineering are those played with by the man in getting the knowledge of the environment underground.3.3 Reforming the Conventional Mining Technologies and Industries with ModernNew technologiesThe major policy of China of reforming the conventional industries with new-and-high techs of great importance and no doubt to its conventional industries. The essential features of new-and-high techs are highly technology-intensive.Just as discussed in the beginning of this paper,speaking with respect to the reforming of mining engineering and coal industry with new-and-high techs,it is essential to introduce merely those ones which enable to make these two industries swiftly commercialized. Since mine is concerned with the natural surround gas of ground,the new techs,however,as those used in aerospace engineering in the care for "going up to sky" when used for 0getting down into the earth in mining engineering practices evidently are needed to make completely different modalities. In 1080s,Berlin Poly }ethnic university had applied optic fiber telecommunication technology- in underground mining,giving rise to abundant interference problems of earth magnetism,electricity and light wave,and the insulation of strata to the conduction electronic waves. The BPM man had the problems s finally tailed,however,through a long time of research work. Therefore,to have the minerals industries well prepared technically for the 21st century,to paying great attention the following fields of study are required3.3.4Making the study of market-economy mineral economics theoriesFor a long time that the mineral economics theory in China had been given distinct features of planning economy,while in the theory itself,mineral resources were not recognized as commodities and had no prices. Consequently,even though the mineral products had prices but were distorted ones making all national mining enterprises non-profitable and to exist depending on governmental policy-subsidization. Now thecountry,however,has changed into socialist market economy,most mineral enterprises radically cannot accommodate themselves to this new situation,in particular,from the point of view of "Enriching the peasants" policy to put forward to the exploitation of mineral resources,the near-term policy of the so-called “wherever there’ water,flow it fast",which had made the mineral industry from the repeated view-point of and the enriching the Pleasants policy,has caused the price deficit due to lowselling-price of minerals into even worse situation of disorder,no-restraint and anarchy of scrambling for extracting the mineral resources putting the mineral industries in a tight spot unabling to feed themselves. Under this circumstance,the importance of undertaking the soft science research right now becomes more conspicuous to the mineral industries than ever before. One can predict that had the theoretical study of mineral economics theory been made ,portent break troughs,that it would radically change the face of our mineral industries.3.5 Relationship between Mineral Engineering and Natural EcologyMining engineering is the removal of rocks and minerals to the surface through excavations from underground deep in the earth or from the ground surface leaving the excavated space so formed. Every turn meters Surface every year subsidence in China. of the commodity flow of mining products reaches billion cubic Obviously it has caused many negative effects,for example:(1)uses of waste rock which results in the damages of farming lands and houses;(2) Large volrefuse and tailings occupy large area of land; and (3) Coal and oil burning products give off waste materials,such as exhaust gas,waste liquids,and solids and pollute the environment. In China,80 percent of 1. 1 billion tons of coal burned as fuel,from which,dust,sulpher and the of NO2and CO2 and the effective less heating effect seriously constitutes a menace to the ecological environment of China and the neighboring countries.4Suggestions opment of to the Science and Technology Circles of the Nation for the Develop-the Mining Subject4.1 An Unguent AppealNo doubt the "flying up into the sky" technology is the one most advanced,however,the getting down into the earth" technology in mining engineering is no less complex,and even more difficult to pin down. It is no wonder that people consider that mineral engineering being much simpler and pay less attention for lack of the knowledge of the resulting in the low rate of mineral recovery and low rate of mineral extracting. Forthis country,but to spend a great many of valuable hard currency to import those actually need not to import raw materials and else,naturally this is not favorable to the development of national economy. Hoping the science and technology circles,in particular their leading departments,renewing their recognitions to this awkward situation,and give necessary support to the urgently-needed topics of research studies of the mineral industries.4.2 National Resource PolicyNational resource policy concerns the future for many generations. Hoping the government population institutions relevant learn Iron the lesson of the past population policy,to take measures as early as possible to have the print up of mineral resources centralized.4.3 Make Ready the SuccessorsTo make ready the successors for the mineral industries and the development of the mining subjects,suggesting to give preferential treatment to the university. Admissions system and the recruitment of mineral workers and set mineral science. Foundation as an important subject independent from the foundations of those. Basic science in the natural science foundation.The aim of writing this paper is to hone that in the tonguing A of this century minim subject in China will have a new prosperous development with the of new technology to theory under the guidance of the national science policy.。
