| 摘 要： | 结合贵州某煤矿的实际情况,分析了导致该矿井瓦斯爆炸事故的多项因素,并使用FTA法(事故树分析法)建立了瓦斯爆炸事故树模型。通过求解最小割集,找出导致矿井瓦斯爆炸事故的途径,根据所求解的最小径集,进行结构重要度分析,找出预防瓦斯爆炸事故的主要方法,最后对该矿进行安全分析和评价。

| Abstract: | In combination with actual situation of a colliery in Guizhou,many factors which cause gas explosion in the colliery are analyzed,and fault tree model of the gas explosion is built by fault tress analysis(FTA).After solving the minimum cut set,the causes of gas explosion are found out.According to the solved minimum cut set,the structural important degree is analyzed,and the main methods of preventing gas explosion are determined.Finally,the safety analysis and assessment for the colliery are carried out. |
