摘　　要：为解决单一安全评估方法在评估煤矿电气火灾风险等级时存在结果偏差较大的问题,提出一种定性与定量相结合的PHA-LEC评估模型。运用预先危险性分析(PHA)对煤矿电气火灾风险系统存在的危险因素及其原因进行辨识和定性分析,结合作业条件危险性评价(LEC)对各因素在系统的现状进行定量分析,通过赋值方式确定单因素的风险等级,并提出相应的安全对策。以S煤矿电气火灾风险评估作为工程实例,验证了模型的可行性和实用性。A risk assessment model integrating the qualitative and quantitative analyses is proposed by PHA-LEC method, aiming at overcoming the shortcomings of single assessment model and improving the accuracy of risk level in coal mine electrical fire. The dangerous and harmful factors in coal mine electrical fire are identified and analyzed qualitatively by PHA, and each dangerous factor of coal mine electrical fire system is assessed by LEC, which analyzes and calculates quantitatively the risk level of each hazard and brings forward the corresponding security measures. Finally,the feasibility and practicality of the model are verified by the engineering example in the risk assessment of S coal mine electrical fire.
