Model And Research On Input-output Of Circular Economy About Comprehensive Development & Use Resource In Coal Company

On the basis of definition for mining, this thesis analyzed classifications of main resources in mining and characters of circulation in mineral resources, discussed the development status of mineral resources in China, in-depth analyzed the excessive destruction and enormous waste caused by extensive operation of traditional exploitation mode in coal mining over time, revealed the current method of coal mining discipline on environmental impact and the reasons for low economic benefits, and then provided a basis for coal resources exploitation and utilization mode. From the perspective of material flow, it quantitative researched the impacts on ecology environment by exploitation and utilization of mineral resources, integrated mining conditions. It built the material flow system of mining resources exploitation and utilization system, discussed that industrial enterprises from"end-of-pipe control"to the"whole process control"shall be inevitable by the study of the ecological damage and environmental pollution causes under market mechanism, and put forward a mining enterprise handling of waste.The thesis comprehensive exposited circular economy and"3R"principles, and applied to the exploitation and utilization of coal mining resources, at the same time, it put forward two types of the recycling economy model for exploitation and utilization of mining resources, one is"Three Differences"which means to take different forms for the development of circular economy in the coal business, business groups and society; the other is"Four Complexes"which means divided the coal mining into exploration and machining by industries and processes, specifically four stages of circular economy model are mining exploration, mining, washing and in-depth processing.It prepared the circular economy development plans of Pingyu coal and power company under"3R"principles, set up input-output model of exploitation and utilization for mining resources, and predicted all indexes in Pingyu from 2008 to 2015, the results show that the company local test of circular economy has achieved obvious results by 2009.The strategy measures for exploitation and utilization circular economy development model of mineral resources was put forward at last.
