From industrial crisis and problems existing in coal mining area,this paper studied many complex problems of the development mechanism of Circular-typed Coal Mining Areas (abbr. Circular-typed Mining Area,CMA) according to related research achievements at home and abroad. It systematically answered five questions on the basis of correct understanding of the connotation of circular economy. Firstly, why did it need to build CMA? Second, which force determined the movement direction of the CMA and how to work? Third, how did CMA run and what was its operation unit? Fourth, how was it controlled and what was its regulatory subject and method? And, how the regulatory target was determined and how it was simulated? Fifth,how to give an objective evaluation of the development of CMA?Based on thorough research on related theories,the CMA theory system was established including the basic concept of CMA, the structure, function, characteristics, process and framework of CMA, the drive mechanism, operation mechanism, regulation mechanism of CMA. At first, a force model of CMA was constructed on the basis of theoretical analysis, and the effectiveness and suitability of the model were demonstrated through theoretical and empirical analysis. It was found that the government political impetus, enterprise technology promoting force, pulling power of market, and lure power of culture from the social public and natural environmental stress force can promote the development of CMA. But the joint force, which was composed of self-weight with development of economic system and the force with environmental bearing capacity, and inertia hinders stress force make the decline in the development of CMA at the state. It was possible to make development of CMA healthy on roads only to make the drive force larger than the down-slide one.Then, with the metaphor of three carriages of CMA, the paper analyzed the run unit of CMA. The operation of CMA was analyzed from the conditions, direction, process and mechanism. With the XR operating philosophy, three-way win-win analysis and coupled with the value chain and ecological chain on the CMA, three-way win-win situation was analyzed. Through the comet model of the circular-type industry network and circular-type community network, it was realized of the triple win of economic benefit of CMA, ecological benefit and social benefit, and the natural system, economic system and social system were harmonious. Through the 3R principle, it was realized communicate effectively in vein industry and artery industry. Case study results showed that, through the reasonable system design, CMA was completely realized three-way win-win situation.Then, through researching on the CMA regulation subject and feedback system the control mechanism of the CMA was constructed. On the basis of the related studies, the index system of CMA was determined. And through Analytic Hierarchy Process (abbr. AHP) the weighing of 24 elements was determined and the key elements were put forward. On this basis, the CMA was simulated through the system dynamics simulation. The simulation results showed that through the key parameters adjustment, it could effectively improve natural resources, land resources, depleting the speed of water decreases speed of mining area, but couldn't ultimately curb the consumption of natural resources.Finally, from the emergy indices the logistics flow, energy flow, value flow, information flow and the population flow were unified. And indicators as convergence of economic, resource, energy and environmental eco-efficiency were established as the evaluation criteria of CMA evaluation. Through empirical studies of Yima and Xuzhou mining area, it confirmed that the emergy eco-efficiency index were effective and could meet the need of the evaluation of CMA, which was a meaningful attempt and contribution of CMA theory.This paper has 113 figures, 43 tables, 226 references articles.
