Study On Complex Network Of Circular Economy In Mining Area Of Ximing Coal Mine In Shanxi Province

Coal is the main energy of our country and plays an important role in the process of national economy and social development.At the same time,the coal as one-time exhaustible resource,people how to reasonably use coal and develop circular economy,has always been a matter of concern.The construction of circular economy system in coal mining area is the form that is adopted to realize the sustainable development and aims at protecting the environment and maintaining the ecological balance.It turns traditional open-loop economy to closed-loop economy,abandons the traditional single-linear economic developmental model "resources-products-waste",and uses the feedback of circular economy developmental model "resources-products-waste-renewable resources ",which can really achieve low consumption,low emissions and high efficiency of use of coal resources.In addition,it can use as little as possible environmental cost and resource consumption to obtain as much as possible economic and social benefits.Based on the theory of circular economy and the method of complex network,this paper analyzes and studies the mining area of Ximing coal mine in Shanxi province.First,this paper discusses the necessity and urgency of implementing circular economy in coal mining area.The development and connotation of the theory of circular economy,the emergence and development of complex network methods and the present situation of circular economy development in China's coal mining area are introduced respectively.Followed by the principle of combining theory and practice,we conducted a survey of coal mining areas.According to the survey,setting coal mining area as an example to build a complex network model of circular economy,applying the Gephi software to analyze and visualize the complex network model data,the result shows that the model works well,but the structure and operation of the model are not perfect yet,and then according to the problems found in the analysis,combining with the actual situation of the coal mining area,improving the complex network model of circular economy and comparing the complex network model of circular economy with the operational results of the actual model.Finally,according to the implemented current situation of circular economy in Ximing coal mining area,this paper puts forward the measures and suggestions to improve the operation effect of circular economy in coal mining area.Summarize the achievements made in the research,as well as the shortcomings and prospects of the paper.The study is based on research and analysis,provides a theoretical basis for the sustainable development of the coal mining area,which is of great significance to the coordinated development of economy and environment.
