Study On Circular Economy Development Mode And Application Of The Coal Industry

The coal industry is one of the fundamental industries in China, and plays animportant role in China’s GDP. Developing cyclic economy is the implementation ofthe scientific outlook on developmentin the cola industry, the sole choice whendiverting its economic development mode, and the inevitable trend of sustainabledevelopment.With the cyclic economy’s development mode of the coal industry as theresearch target, based on the summary of concerned research achievements in Chinaand abroad, this research employs theories of clean production, eco-industry parks,industrial ecology, cyclic economy and sustainable development. Throughinformation retrieval, field visits and systematic thoughts, according to basic theoriesof the cyclic economy, the research carries out in-depth discussions and systematicanalysis into the development of the cyclic economy in the coal industry from the newperspectives of industrial ecology and value creation.From the perspective of industrial ecology, the development mode of the coalindustry’s cyclic economy is the formation of ecological system of the mining areaunder the co-effect of natural, economic and social factors, with the greenproductivity as theimpetus of the social development. The development mode of thecoal industry’s cyclic economy is a combination with its own characteristic ofco-existing. The research takes a systematic analysis into the co-existing combinationof the coal industry from the unit, roles definition, locations definition, connectingmethods and organization methods, and obtains the development mode system of thefive factors.From the perspective of value creation, the cyclic economic development modeof the coal industry breaks the traditional boundaries of customers, demands,industries and industrial chains. It includes stakeholders such as residents in themining area and the government as customers; breaks the boundary of the coalindustry, taking the tri-win situation of economic, social and ecological effects as wellas the whole value as the priority; and breaks the boundary of industrial chain,arriving at a win-win cycle in the whole society, meeting the demands of fulldevelopment of resources, laddering usage of the energy and minimum discharge ofthe pollution.In order to evaluate the cyclic economic development mode and its effectivenessin the coal industry, this research employs analytic hierarchy process to build up theevaluation index system of the cyclic economic development in the industry. Basedon the marks given by experts, it obtains relative weight of all parameters, anddelivered evaluation to Xinwen Mining area, Huannan Panxin Mining area, and TiefaMining area. The results have shown that Xinwen mining area is at an advanced stageof cyclic economic development, whilethe other two remain at the medium stage.In the end, the system dynamics is employed to carry out simulation on thecyclic economic development mode in Tiefa Mining area. By changing the parametersthat affect the mining area, it chose four simulation parameters to change the impactstowards the environment, economy and the society of the mining area. The conclusion of the research: changes of parameters have obvious impacts to the farmlands, therecoverable reserves, water resources and the total volume of exhaust gas. It is, withscientific mining and planning, possible to slow the reduction of the farmland, waterresources and the recoverable reserves, lower the total volume of exhausted gas, andraise the mining area’s GDP, while maintain the economic increase of the mining area.The simulation results point out the development direction of cyclic economy of thecoal industry, and is benefit to the building of cyclic economic development mode ofthe mining area.
