事故树分析法在煤矿水灾安全评价中的应用

Application of Fault Tree Analysis in safety assessment of coal mine floods

通过对煤矿水灾的事故树分析,得出了导致煤矿水灾的17个基本事件。应用事故树分析中的最小割集、最小径集和结构重要度,对煤矿水灾进行了研究。结果表明,煤矿水灾不发生所必须的最低限度的基本事件集合,即最小径集有35个,其中,合理的防煤矿水灾设计和杜绝开采煤岩柱是预防煤矿水灾的最重要途径。

Through the Fault Tree Analysis in colliery flood shows 17 basic events leading to coal mine floods.Fault Tree Analysis minimal cut sets,the path set and the important degree of the structure on coal mine floods are applied in a study of coal mine floods.The results show that the non-occurrence of coal mine floods requires the minimum of 35 sets of basic events,i.e.minimal path sets,of which rational design to prevent floods in coal mines and prohibited mining of coal pillars and rock pillars are the most important ways to prevent coal mine floods.
