In this paper,the mechanical and electrical accident risk control of Donglin Coal Mine was taken as the analysis object.The "list of coal mine electromechanical accident risk" was listed.By using the "coal mine electromechanical accident risk collection table",the results of "coal mine mechanical and electrical accidcnt risk damage" and "the possibility of coal mine mechanical and electrical accident risk" were calculated," coal mine electromechanical accident risk damage consequence" was drawn.According to the results of coal mine electromechanical accident risk assessment,the dynamic monitoring mechanism of mechanical and electrical accident risk of coal mine was put forward,and the risk of coal mine electromechanical accident risk was proposed.Management standards,technical measures,managemcnt measures and emergency preparedness was proposed,too.Through the research,this paper provides an application example for electromechanical accident risk management of state-owned coal and gas outburst mine in Chongqing.

In this paper,the blasting accidents in 8 major coal mine accidents in Donglin Mine are taken as the analysis object,and the "six tables and one chart" of Chongqing Municipality Emergency Management Guidelines for Risk Management(Trial) is taken as the core framework to carry out coal mine accident risk evaluation.First,make a list of risk about coal mine accidents,and make a table of collected imformation of coal mine accident risk;secondly,calculate the risk of and its possibility of coal mine accident,draw a matrix of accident risk in coal mine,and the risk degree value of coal mine blasting accident was obtained;third,according to the summary results of risk assessment for coal mine blasting accident,the dynamic monitoring mechanism of dynamic risk of coal blasting accidents is formed,management standards,technical measures,management measures and emergency preparedness measures are also put forward.

Aiming at the frequent occurrence of coal mine roof accidents,by adopting the method of blasting accident risk identification acquisition,risk assessment,risk prevention and control methods,and the "six tables and one chart" of Chongqing Municipality Emergency Management Guidelines for Risk Management(Trial Implementation) are taken as the core framework to carry out coal mine accident risk evaluation.First,make a list of risk about coal mine accidents,and make a table of collected imformation of coal mine accident risk;secondly,calculate the risk of and its possibility of coal mine accident,draw a matrix of accident risk in coal mine,and the risk degree value of coal mine roof accident risk was obtained;third,according to the summary results of risk assessment for coal mine roof accident,the dynamic monitoring mechanism of dynamic risk of coal mine roof accident is formed,management standards,technical measures,management measures and emergency preparedness measures are also put forward.This paper provides a demonstration case for roof accident risk management of typical medium-sized coal mines with more types of disasters.

针对新形势下煤矿安全管理与防控工作特点,在总结煤矿安全事故发生的规律的基础上,坚持"安全第一,预防为主,强化隐患排查,注重过程控制"的指导思想,将预警机制引入煤矿安全管理之中,着力构建安全管理与防控工作新模式——煤矿安全预警机制,取得了较好的实践效果。
