【摘要】 根据矿井采煤面瓦斯爆炸的一些典型事例,概括出导致瓦斯爆炸的基本事件,编制了采煤工作面瓦斯爆炸事故树。应用事故树分析中的最小割集、最小径集和结构重要度,对矿井采煤工作面瓦斯爆炸事故进行了研究。结论表明,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。更多还原

【Abstract】 Based on some typical examples of gas explosions on the coalface,the basic events resulting in gas explosions are generalized and a fault tree is drawn.Gas explosion accidents on the coalface of mines are studied,using minimal cut set,minimal radius set and structural importance.The conclusion shows that gas explosions can be prevented only by keeping gas consistency under tight control and putting an end to every possible fire source.更多还原
