Gangue coal production subsidiary, low calorific value, complex composition, is a \In the past, in addition to a small number of high calorific value of coal gangue used, a large number of low calorific value coal gangue forced to stockpiling is not only a waste of resources, but also occupation of the land, pollute the air and harm the health of residents around the mines, there is an urgent need for comprehensive utilization and ecological disposal. Promote recycling economy in China, the development of \practical value. This article as energy base in China's Shanxi Province as the study area, the gangue ecological disposal mode for the study, the use of the combination of field research, quantitative and qualitative analysis of the combination of theoretical analysis and empirical research methods, Shanxi coal gangue utilization and disposal of the case, the existing problems, ecological disposal methods, ecological disposal mode, the Ecological and disposal and policy proposals and other issues, discussed in a more systematic, to provide examples and Shanxi and other relevant regional coal waste disposal. The main contents and conclusions are: (1) analysis of coal gangue resources in Shanxi Province and Their Disposal, the status quo, said: Shanxi coal production, the large number of mines, the area is more dispersed, resulting in a huge coal gangue resources, the end of 2009 total stockpiling amounted to 613.339 million tons, is expected to the end of 2015 but also count 1,006,150,000 tons; disposal only 30% the ecological disposal rate even lower than this figure; the gangue component is complex, diverse, increasing the use inappropriate stockpiling and disposal of difficulty; may cause air pollution, destruction of water pressure accounting for land and other secondary disasters. (2) to explore the theory and methods of the gangue ecological disposal, pointed out: Ecological disposal of coal gangue is different from the general disposal to ecological economics, ecological restoration, circular economy theory must be based on follow Category centralized disposal, resource priority , place disposal the full management principles, use of ecological landfill, the direct use of four methods of the processing: refining, greening and reclamation. (3) to the recycling economy and ecological industry chain guide, Pingshuo mine, for example, try to build a model of industrial ecological disposal. Suitable for the higher calorific value of coal gangue gangue - power generation - building materials, coal gangue - washing - useful minerals extraction \pits and subsidence area, the formation of \development of eco-tourism industry and disposal mode. (4) the use of qualitative and quantitative analysis, analysis of the potential benefits of Shanxi Province, the implementation of ecological disposal generated. : Shanxi Province, coal gangue comprehensive utilization and ecological disposal, can generate considerable economic benefits, estimates, comprehensive utilization of coal sales revenue of about 950 billion yuan, only the \yuan, profit of 48 billion yuan, a substantial contribution to the mining area of ??economic growth; social benefits is mainly manifested in increased employment opportunities; environmental benefits, mainly in terms of new land, to reduce SO2 emissions. (5) for the gangue ecological disposal problems in the solutions and national and local level policy recommendations at the policy level, simplify project approval procedures, and related industries to encourage enterprise development waste rock and gangue power generation and coal gangue brick project to provide reasonable preferential policies, the establishment of special funds and other policy recommendations, an important guarantee for coal waste disposal.
