2、led gradually, some also lead to serious results. Therefore, the balanced relation of “resources mining - environmental protection - mining area sustainable development” is a very important topic of resource development in our country in the 21st century, named “green mining”. In accordance with thi
3、s balanced relational mining area development pattern, it is called “the green mining area” pattern of the sustainable development. One of its core contents is to be aware of “green mining”.Keywords: Mine environment; Resources mining; Green mining1. The brought forward of the green miningNowadays,
4、fossil fuels still occupy the dominant station in the worlds energy structure, as shown in Figure 1. But as the expansion of industrial production and advancement of the industrial technique, the demand for energy is growing, at the same time the fossil energy resources have gradually depleted, and
5、the unrestrained use of fossil energy has given rise toincreasingly serious environment problems.nuclearenergy 4%hydrpower6% boilmass15%gas17%coal24%oil34%Fig.1. the situation of the world energyAt present, the problems of energy and environment have become the major focus of global concern, sustain

At the sametime, environmental problems of mine have also attracted large concerns and attention of the中國礦業(yè)大學(xué) 2012 屆本科生畢業(yè)設(shè)計第 122 頁international community. With the increasing depletion of fossilenergy and the environmentgetting worse, carry
7、ing out the research of the technology of the green mine in the mining area, achieving a clean and efficient utilization of energy, the development and utilization of biomass energy has become a global issue. The father and the repair of the zoology in the mine area is an inevitable requirement in t
8、he mining industry of the world mining area, it will be an inevitable and important issue of the environment and the development of the world.Green mining follows the economic cycle of the principles of green industry, which coordinates the formation of mining and the environment, it is a technology
9、 of exploitation which achieves the goal of low production, high efficiency, low emissions. Green mining in the coal mining area is the only way for the healthy development of the coal industry, for it can prevent or reduce the adverse environmental impacts from coal mining as much as possible, so a

Coal mining destroys water resourceFig.2. coal mining area subsidence induce serious soil erosionThe destruction of water resource caused by the
11、coal mining is mainly manifested in two aspects. On the one hand, it is in the process of the coal mining, because of man-made drainage and dewatering mining, the formation of the hydraulic fracture of the natural aquifer coal dewatering would result in the water levels drop significantly in a large
12、 area of the ground. A major mining area of water supply dried up, making surface of earth dry, that will destroy the natural landscape, the reduction of agricultural production, which can cause serious desertification and soil surface, shown in Figure 2.On the other hand, the exploitation causes th
13、e pollution of surface water and groundwater. Mine water, waste heap leaching of water, coal preparation waste water containing such as coal, rock flour suspended solids and solubleinorganic salts. In western of China, Huang-Huai area, the mine water has salinity highly, and中國礦業(yè)大學(xué) 2012 屆本科生畢業(yè)設(shè)計第 123

Discharging the waste water into the surface river, sea and reservoirs, and others would lead to more serious pollution of water resources, lead to the earths poor and causes vegetation pollution in the mining area, it has also affe
15、cted the sustainable development of agriculture seriously.2.2. Coal mining results in the destruction of land resourcesThe destruction of the land resources caused by the coal mining are displayed in two aspects ,on onehand, the surface subsidence and waste pressure account for mainly in the well wo
16、rks mining, on the other hand, the hurt and foreign direct dug dump pressure account for mainly in the open-pit mining, as shown in Figure 3.A large number of harmful gases such as SO2, CO2, H2S and nitrogen compounds, such as dust was discharged during the process of thespontaneous combustion of wa

18、assive virulent noxious gasesIn the underground ore bed, there are massive virulent noxious gases, like CH4, CO, CO2, SO, SO2,H2S and so on. Because mines, loose and carries the massive dust row after the mine ventilation to the atmosphere. Approximately 10,000,000,000 m3 of CH4 is discharged into t
19、he atmosphere from the coal mining every year in our country, the emissions dust approximately 400,000 tons, not only this reason has caused the serious environmental pollution in the mining area , as shown in Figure 4. Moreover, this will lead to the consequence that hundreds of thousands of people
20、 may get pulmonary disease.2.4. Traditional methods of exploitation create ecological and environmental problems(1) Coal mining causes the migration of the strata, it causes the water and the gas flowing in中國礦業(yè)大學(xué) 2012 屆本科生畢業(yè)設(shè)計第 124 頁the rock layer and causes coal mine gas accident and the incidents
21、of water bursting. At the same time, the gas is discharged into the atmosphere which will produce environmental pollution. Coal mining immediately influences ground water outflow, even causes the land desertification. According to the calculations, the coal mines the national average ton coal water
22、price is 2 t, northern region 10 t, reaches 47 t high, the coal mine displacement has occupied the northern area karst water resources 19%, the use factor only account for 30%.(2) Coal mining causes the rock layer migration, then causes settlement of the surface and damage of the farmland and the bu
23、ilding facilities. According to the statistical data, the destruction which because of the nation coal mining occupies land of 430,000 hm2, picks ten thousand tons coal collapse land 0.2 hm2 every time equally, every year increases the collapse approximately 20,000 hm2. Piles up under the building,
24、the water body and railroads coal resource reaches tens of billions t to be unable to mine, the cause mine pit discards ahead of time.(3) Coal mining forms bulk depositions in ground gangue, both takes the fertile farmland, and causes the environmental pollution. Already accumulated gangue 3,000,000
25、,000 t, and was increased every year still by 1.5 200,000,000 t quantities. In the national 1500 hillocks has 140 in the spontaneous combustion, to the atmosphere, the land and the environment causes the serious pollution.(4) Along with our country mine pit mining depths unceasing increase, the freq

Measures to reduce the sink(1) Backfill miningThe backfill mining is backfill the mining goals by useing the foreign materials, including the scoop up last bit of water granulated substance backfill, the waste filling and so on.(2) Banding mini
31、ngStrip mining is currently under the control of the building of surface coal mining subsidence, which is most widely used. Banding mining is currently the main technical way to control the surface subsidence when coal mining under the building in our country. And the technical way is widespread. Th
32、e banding mining principle is the coal bed which must mine divides the quite regular banding to carry on mining, picks one, and keeps one, the banding virgin coal support overburden which the use retains, thus the reduced cap rock settlement, controls the surface the migration and the distortion, se

Coordinated mining technologies of coals and gasAccording to the differences of the mine method of coal bed methane ,the source of the pressure of gass and the mine method of the pressure gas ,we have constructed the technical system chart of“a to
39、tal of coal and coal-bed methane mining” , as shown in Figure 5.3.4. The processing of the gangue in the mineOne problem of green mining technologies is the processing of the mine shaft gangue. The first step is to strengthen the maintenance technology of the coal lane, so as to create less or no wa
40、ste rocks. With the increase of the mining depth, rocks Lanes digging will be inevitable, therefore the gangue will not be taken out of wells, it can be used as filling material. Thus, there is a technology and the system question a gangue down-the hole treatment underground, the key is the cost of
41、it. Another problem is whether the gangue can be disposed on the ground for recycle waste, for example, change it into the building material, the hydraulic fill and so on .After all, the processing of the gangue on the ground is simpler than underground treatment.technology system of coal and gas co

45、the drill hole platoon, supplying the users. It is a kind of Comprehensive green mining technology.4. The significance of the green mining in the mining area(1) The exploitation of green mining requires the improvement of the technology level. Chinas coal industry havent even as a whole, following t
46、he path of extensive development for a long time, intensive level of production is very low. The exploitation and innovation of multi-dimensional and multi-angle arethe necessary requirement for Green mining.(2) Green mining systems require the efficient use of products. Greenpeace demands the explo
47、itation of resources in a broad perspective within the framework of the coal mining area,water, coal-bed methane, land, coal gangue, as well as in other nearby deposits, and otherresources available, we shouldminimize the negative impact on the environment while in thepursuit of the best economic an
48、d social benefits while.(3) The green mining requests a comprehensive evaluation of the enterprises, considering the ecological environment. Exploitation of the large green uses the way of ecological system to look on and evaluate the economic activities of enterprises, to achieve sustainable develo
49、pment of the ecological system. Which requests them to pursue their own economic benefits, it also requests them to take full account of the social and environmental benefits.5. ConclusionsIn the early 1980s, It was called in the United Nations that: it is necessary to study the basic relations of t
50、he natural, the social, the ecological, the economic as well as the process of the use of natural resources, so as to ensure the sustainable development of the world. At this point, sustainable development caused widespread concern in all walks of life and identity on a global scale, our government
51、have also put the sustainable development into the Agenda of 21st. in the near future, the economic cycle (Recycling Economy) refers to follow the natural ecosystems of material circulation and energy flow to follow the law of economic reconstruction, economic activities will be highly efficient and
52、 orderly organization as a resource utilization - the green industry - renewable resources closed Material-energy cycle feedback processes, to maintain the economic production of low quality, low-waste, so that the impact of economic activity on the natural environment damage to a minimum. It is dif
