Study On Circular Economy Development Mode And Evaluation Of Coal Exploitation

From last century, there emerged the global problems, such as population explosion, resource shortage, environment deterioration and climate warmer, which forced people to raise a brand-new view for development, named sustainable development. After reforming and opening to the outside world, due to the traditional mode of economic development, resource exploitation and consumption in our country boomed, which make the frangible eco-environment and the limited natural resources face the highest development pressure ever since the outset of human history in China.For a long period, coal has played a very important role in our national economy as a mainstay of energy source industry. With the continuously rapid increase of national economy, demand of energy source in our country rises increasingly. The traditional energy source mode of high exploitation, high emission and low usage rate led to not only waste of resource but also environment pollution. Furthermore, the mode was not able to meet demand of modern economic development. Therefore, in the new century, how to find a way of integrating produce mode while saving resource and keeping sustainable development becomes a very important strategic task. Circular economy, as an advanced development mode for harmonizing the problems among resource, environment and economy, is destined to be the choice for coal concerned enterprises to explore new industrial way and keep on developing. Currently, researches and practices for circular economy in China has been spread gradually. There is no doubt that combining the circular economy concept and the fact of Chinese coal concerned enterprises in order to find a mode of circular economy for coal exploitation is significant both in theory and for practice.According to the research principle of combining qualitative and quantitative analysis, combining criterion and demonstration analysis, the paper starts with research for resource waste and environmental pollution in the process of coal mining. On the basis of overseas theories and practices of circular economy, the paper constructs the developmental mode of circular economy for coal exploitation. First, the paper studies the circular economy development mode from the aspects of production, technology and management. Second, it establishes a comprehensive model of evaluation to estimate the effect of circular economy for coal exploitation, and implements demonstration analysis, thus providing a kind of powerful control approach. Last, it suggests that adoptable national policies, laws, concrete measures should be stipulated for circular economy in coal mining.
