Abstract: For the problem that Miner’s mood may lead to unsafe behavior, a game model of “miner emotion supervision and miner’s unsafe behavior” was constructed based on the theory of evolutionary game theory. The solution and analysis results of the model showed that the potential risk value of emotion to the unsafe behaviors of miners, the cost of emotional adjustment for miners from supervisor and the cost of safe operation of miners are positively correlated with the unsafe behaviors of miners; the cost of unsafe behaviors caused by miners’ emotion and the loss value that they should bear after safety accidents are negatively correlated with the unsafe behaviors of miners. This paper proposes some measures to improve the efficiency of coal mine emotional regulation and reduce the unsafe behaviors of coal mine by means of human intervention.
