In order to solve the lack of population change in classical evolutionary model,an evolutionary model on coal mine production safety supervision is developed based on prey-predator model.The evolutionary equilibrium of different behavior bodes and its characteristics in the model are analyzed by the theory of system dynamics.The symbioses of different parts in the coal mine safety supervision system are simulated.The results show that the symbiotic evolutionary center point between different behavior bodies in the coal mine safety supervision prey-predator model depends on the coefficient.One ratio is the net natural growth coefficient of illegal production in coal mining enterprises and divided by ability coefficient.Coal mine safety supervision department found illegal production and punishment.The other ratio is the natural mortality coefficient of coal safety supervision department according to the progress of society and technology divided by the dependent coefficient of coal mine safety supervision based on illegal production of coal enterprises.This research conclusion can effectively explain the variation characteristics of coal mine safety accidents in China.%针对演化博弈缺乏种群数量变化的不足,建立了基于食饵-捕食者模型的煤矿生产安全监察演化模型,利用系统动力学理论分析了不同行为主体共生演化模型的平衡点及其特征,最后对食饵-捕食者模型的共生演化过程进行了仿真分析.研究结果表明,煤矿安全监察系统食饵-捕食者模型中不同行为主体之间共生演化的中心点取决于作用系数,即煤矿企业违规生产的净自然增长系数与煤炭安全监察部门发现煤矿企业违规生产行为并依法惩处系数的比率、社会技术进步等各种原因导致的煤炭安全监察部门自然死亡系数与煤矿企业违规生产行为对煤炭安全监察行为的供养系数的比率.研究结论可以有效解释中国煤矿安全事故变化特征.
