摘　　要：针对煤矿瓦斯爆炸事故的预防问题,采用事故树安全评价法,找出瓦斯爆炸事故的直接原因事件和基本原因事件,构建了煤矿瓦斯爆炸事故树模型。运用布尔代数法则,得出煤矿发生瓦斯爆炸事故的最小割集有182组,最小径集有4组。再通过最小割集、最小径集的基本原因事件的结构重要度系数的运算结果,得出预防煤矿瓦斯爆炸的安全评价结论,对煤矿行业监管及安全管理有参考价值。Aimed at the prevention of gas explosion in coal mines,based on the ways of fault tree model for coal mine gas explosion acci-dents ,by adopting the safety evaluation method of fault tree analysis, the direct reason and the basic reason for the gas explosion acci-dents were obtained,and the fault tree model for coal mine gas explosion accidents was finally established. According to the Boolean al- gebra,it was obtained that the least cut sets of gas explosion accidents is 182,and the least path sets is 4. Through analyzing the calcula-tion results of the structure importance coefficient for the least cut sets and the least path sets, the conclusion of the safety evaluation for gas explosion accidents of coal mine can be obtained, which has a certain reference significance for safety management of coal mine in-dustry.
