摘　　要：为预防煤矿特别重大瓦斯爆炸事故,开展事故发生规律和致因研究。统计分析最近几十年发生的126起煤矿特别重大瓦斯爆炸事故,运用基于故障树(FTA)的贝叶斯网络(BN)方法,分析各危险源对事故影响的重要度,建立纵深防御管理模型。结果表明:煤矿特别重大瓦斯爆炸事故主要是由通风与瓦斯管理混乱、电气火花和爆破火焰引起,且大多数发生在采掘工作面;局部通风机随意停开、采空区瓦斯、电缆破损短路等是预防特别重大瓦斯爆炸事故的管控重点。In order to prevent extraordinarily serious gas explosion accidents in coal mine,it is necessary to study the laws and causation of accidents. Based on the analysis of the 126 cases of extraordinary serious gas explosion accidents,the method of fault tree analysis-Bayesian networks was used in analysis of importance of hazards in causing accidents. And then a defense-in-depth management model was built. The results show that extraordinarily serious gas explosion accidents are caused mainly by ventilation and gas management confusion,electric sparks and blasting ignition,that most of the accidents take place at coal faces,and that for the sake of preventing the accidents,local ventilator random open-close,accumulation of gas in goaf,and cable breakage should be avoided.
