基于GRA和AHP的煤矿一般事故防控研究

Research on Prevention of General Acidents in Coal Mines Based on GRA and AHP

为研究近几年我国煤矿一般事故的规律特点,以2019—2021年的煤矿一般事故统计为研究对象,通过轨迹交叉模型分析了一般事故的规律特点。构建了煤矿一般事故影响因素分析模型,通过灰色关联分析法研究了一般事故的影响因素,利用层次分析法研究了一般事故防控的重点和方法。结果表明:一般事故发生与安全管理密不可分,且与煤炭企业数量、从业人员数量关联度较大,需进一步提高煤炭企业效率、减少作业人员。一般事故防控受辅助运输装备智能化、取消绞车和团队互相监督等影响较大,需在“三违”控制、职工风险意识、智能化建设、制度建设、制度考核等方面同时发力,提高煤矿一般事故防控能力。

In order to study the characteristics of general accidents in coal mines in China in recent years,taking the statistics of general accidents in coal mines in years of 2019-2021 as the research object,the characteristics of general accidents were analyzed by trajectory cross model.The analysis model of influencing factors of general accidents in coal mines was constructed.The influencing factors of general accidents were studied by grey corelation analysis.The key points and methods of general accident prevention and control were studied by analytic hierarchy process.The results show that the occurrence of general accidents is closely related to safety management,and has a great correlation with the number of coal enterprises and the number of employees.It is necessary to further improve the efficiency of coal enterprises and reduce the number of employees.The general accident prevention and control is greatly affected by the intelligentization of auxiliary transportation equipment,the cancellation of winches and the mutual supervision of teams.It is necessary to work together in the aspects of"three violations"control,employee risk awareness,intelligent construction,system construction and system assessment to improve the general accident prevention and control ability of coal mines.
