wind的回答：The twentieth century is the most energy consumption in human history, a century development of industrialization of energy supply, high requirement put forward with the natural protection consciousness of nature, human beings are crazy and destruction. The development of social economy makes human increasing demand for energy, but the nature of resources but not the inexhaustible, if not make corresponding human effort, in the near future will face energy shortage, production environment deteriorated. In the 21st century, coal enterprises implement the development of recycle economy mode of coal industry, is the inevitable choice of deepening the sustainable development, the development of coal mining enterprises to find the direction. Based on the development of circular economy in coal enterprise, based on the theory of general significance of coal industry and ecological circular economy development mode of coal enterprises apply, scientific development of circular economy and the measure index system of coal enterprise circulation economy development level of evaluation model. This paper analyzes the recycling economic principle of coal enterprise of circular economy development guidance, gangue, coal gas, mine water treatment of circular economy industry chain, the construction of assembly, by extension, and the coupling, coal enterprises by multiple forms of horizontal and vertical industrial chain. So as to form a three-dimensional model of the circular economy construction. Constructing circular economic index system of coal enterprises. Using analytic hierarchy process to index system for weight assignment. Application of multi-grade fuzzy comprehensive evaluation of circular economy development level, is able to overcome the fuzziness of attribute index, identify the coal enterprise of circular economy development situation and restriction factor, get more objective comprehensive evaluation results. wind的回答：The twentieth century is the most energy consumption in human history, a century development of industrialization of energy supply, high requirement put forward with the natural protection consciousness of nature, human beings are crazy and destruction.
