用事故树法确定煤矿防治水安全检查表

Application of fault tree analysis to establish safety checklist for groundwater inrush in underground coalmines

摘要: 为对煤矿防治水系统做出专项安全评价，采用了事故树分析的方法。利用计算机编程分析可以得出煤矿突水事故树最小割集和基本事件的结构重要度。根据事故树基本事件及其结构重要度建立防治水系统专项安全评价指标体系与安全检查表。采用该方法实现了某煤矿六采区水体下开采的防治水专项安全评价。得出突水事故树的最小割集共116个以及基本事件的结构重要度。依此建立了六采区防治水系统专项评价指标体系与安全检查表。检查评价该矿安全等级为低度危险，并提出整改意见。

Abstract: This paper presents the application of the fault tree analysis to assess the risk of groundwater inrush in coalmines.Computer programming was used to calculate the minimal cut set and structure importance.The results of computer programming for a coalmine illustrate that the number of minimal cut set is 116.And the structure importance of every basic event was also calculated.A safety assessment index system and a special safety checklist were established based on these results.The result of safety assessment is low risk.And amendments were proposed.
