Abstract: Local government ecological environment supervision departments and coal enterprises are the main responsible entities for the implementation of ecological restoration in mining areas.In view of the current problems of poor execution of land reclamation in my country's coal mine areas and insufficient departmental supervision.This paper established a three-party interest body involved in mine land reclamation:a three-party game model of coal enterprises, local governments, and residents of mines.By solving the mixed strategy Nash equilibrium, three-party behavior evolution stabilization strategies and laws are simulated numerically, and Zhaogu 1st mine is selected as the research object for empirical research.The researches show that the probability of reclamation of coal enterprises is mainly affected by the probability of local government supervision.The initial willingness of enterprises to reclaim also affects the government's regulatory behavior.The government environmental performance and image loss should be included in the evaluation of government work to promote government supervision.The government can appropriately increase the amount of security deposits or fines to increase the willingness.At the same time, special supervision and reporting channels should be opened and appropriate supervision subsidies should be provided to encourage the public to participate in supervision.
