矿井采煤面瓦斯爆炸事故树分析

Fault tree analysis on gas explosion at coal face

根据矿井采煤面瓦斯爆炸的一些典型事例 ,概括出了导致瓦斯爆炸的基本事件。应用事故树分析中的最小割集和结构重要度 ,对矿井采煤面瓦斯爆炸事故进行了研究。结果表明 ,严格控制瓦斯浓度 ,杜绝一切火源 ,是预防矿井瓦斯爆炸的基本途径。

Based on several typical examples of gas explosion occurred at coal face,the basic events of gas explosion are summarized.By applying the minimura cut sets and structure importance of fault tree analysis,the accidents of gas explosion at coal face are studied.The results show that to put emphasis on controlling the density of gas and fire resource is an essential way to prevent gas explosion at coal face.It is of great significance to guide the safety in production at coal mines.
