Abstract
Considering the limited rational behavior of coal-mine enterprises and regulatory authorities, this paper studies the game problems in coal-mine safety production based on evolutionary game theory. The game strategy of coal-mine enterprises is described as the degree of effort on security, furthermore, the probability of safe production in coal-mine enterprises is defined. By introducing the speculative behavior of coal-mine enterprises, an evolutionary game model among national supervisory authorities, local regulatory authorities, and coal mining enterprises was established. Analyzing the model and performing numerical experiments on the results, it was found that the costs that the local supervisory authorities pay to supervise coal-mine enterprises and the rewards given by the national supervisory authorities to the local supervisory authorities can affect the evolution process and even change the evolution stability point. The research conclusions could provide reference for related research on coal-mine safety supervision.
