Research On Game And Simulation Of Coal Mine Safety Supervision

Coal mine safety is the life of coal mine production.At present,my country has made great achievements in coal mine safety,but safety accidents still occur from time to time.Sudden coal mine safety accidents will cause huge loss of life and property.Based on my country's current coal mine safety production management system,using evolutionary game theory to study the coal mine safety supervision system.This paper sorts out the current problems in coal mine safety supervision,establishes a game model based on the safety and economic interests,and divides the games in the coal mine safety supervision system into three types,namely,single group evolution game,double group evolution game and coal mine safety supervision system Evolutionary game.The game evolution process of single-group and double-group evolution game models composed of limited rational individuals is analyzed,including:single-group games and double-group games of supervisory agencies,regulatory agencies and coal mining enterprises,and single-group game models of miners,through calculation Copy dynamic(RD)to solve the equilibrium stable point of single group game and double group game,and conduct equilibrium point stability analysis to obtain the effect of parameter changes on the equilibrium point.It is found that the coal mine enterprise lies in a certain kind of two-group game of supervisory and regulatory agencies.There are fluctuations in the situation,and the two sides of the game choose different strategies according to the changes in their own returns at different times.This situation will always be volatile according to the choices of the two sides of the game.Simulate the evolutionary game of coal mine safety supervision system,study the impact on coal mine safety supervision system from both macro and micro agents,understand the impact of individual behavior on the overall system,and find that due to the influence of human acceptance probability Reason delays the time when the system reaches the stability of the evolutionary game.Using the network analytic hierarchy process(ANP)to analyze the weight of the parameters in the coal mine safety supervision system,it was found that the penalties,safety investment costs and violation benefits have a greater impact on the system.Through the simulation analysis of the impact of the three parameters,it was found that the enhancement The work intensity has basically no effect on the improvement of the production status of the coal mine enterprises.Only by controlling the benefits and costs can the coal mine enterprise consciously conduct safe production.
