煤矿本质安全化管理体系建立及其应用的探讨

Establishment of Inherent Safety Management System in Coalmine and Its Application

运用安全系统工程中的事故树理论,以瓦斯爆炸事故为例分析了煤矿中的7类主要事故,并得出相应的事故树。通过对事故树的定性分析,得出事故树的最小径集和基本事件重要度排序。进而可预测基本事件的发生所能够导致的结果,可根据各基本事件的重要度排序,确定避免发生事故应采取的基本措施,并建立了煤矿本质安全化管理体系。设计出煤矿本质安全化管理体系的软件,并以瓦斯爆炸事故为例,分析了该管理体系在实际中的应用效果。

By applying Fault Tree Analysis （FTA） in safety system engineering and taking gas explosion as an example, seven main kinds of accidents in coalmines were analyzed and corresponding fault trees were set up. After a qualitative analysis of these fault trees, the minimal path sets and the important degree sequence for each basic event were obtained, according to which results caused by basic events could be forecasted and basic measures for accident avoidance could be decided. Based on the above research, inherent safety management system in coalmine and its software were designed and established. Finally, the practical effect of this management system was illustrated by gas explosion accident.
