Abstract: In order to explore front-line miners' safety behavior strategy, a two-party stochastic game model with Moran process was established based on the perspective of job insecurity under limited number of safety inspectors and front-line miners. The influence of different factors on the strategy of game players was explored, and the results were verified by numerical simulation. The results show that, in a certain range, the increase of psychological costs such as job loss insecurity and interpersonal insecurity is beneficial to the improvement of safety inspectors' behavior, but not to the improvement of front-line miners' behavior. In addition, safety risk transfer coefficient, safety behavior cost, strategy mutation rate and the number of players in the game also affect the strategic choice of safety inspectors and front-line miners.
