基于事故树的煤矿瓦斯爆炸机理分析

Analysis of coal mine gas explosion mechanism based on fault tree

瓦斯是煤矿生产过程中的重大灾害之一,直接威胁着煤矿井下的生产安全及人员生命财产安全。通过辩识危险源、分析瓦斯爆炸的机理,在此基础上建立了煤矿瓦斯爆炸事故树模型,计算出不同因素对事故产生的结构重要度。根据事故树分析结果提出一系列预防瓦斯爆炸措施,为防治瓦斯事故提供了理论依据。

Gas is one of the major disasters in the coal mine production process,which directly threatens the personnel and production safety in the coal mine.By identifying dangerous sources and analyzing the mechanism of gas explosion,the fault tree model of coal mine gas explosion was established,the structural importance of different factors to the accident was calculated,and the measures for preventing gas explosion were put forward,which provides a theoretical basis for preventing gas accidents.
