| 摘 要： | 冲击地压灾害是矿山深部开采的难题之一,采用事故树分析冲击地压事故发生的原因、发生概率,对于矿山灾害防治具有重要意义。以平顶山十一矿为实例,收集了该矿2002—2010年发生冲击地压事故的资料与数据,在此基础上建立了该矿的冲击地压事故树;运用布尔代数法确定了事故树的最小径集和最小割集,并计算出顶事件发生概率和事件发生的各基本事件的概率重要度、关键重要度和结构重要度,对基本事件重要性进行排序,最后对矿井冲击地压事故的原因进行了分析,并提出相应的安全对策。

| Abstract: | Rockburst disaster is an important problem in deep mining,while fault tree can analyze the reason and probability of rockburst.This work has important meanings for mine disaster prevention.With Pingdingshan 11th mine as an example,the paper collected the documents and data of mine rockburst accidents between 2002 and 2010,and the fault tree was established.Then,the minimum diameter set and cut set were confirmed with Boolean algebra.The occurrence probability of the top event and the probability importance,... |
