摘　　要：利用故障树分析法对矿井提升机的立即施闸故障进行分析,定性地分析了立即施闸故障6个影响因素之间的逻辑关系,定量地计算了引起立即施闸事故事件的各个因素的概率。计算了立即施闸事故的影响程度即重要度,并将得到的重要度概率按大小排序。为快速找到故障位置提供了数据依据,也为系统的设计修改提供了科学参考。Analysis of mine hoist brake application immediately fault was analyzed by using fault tree, qualitative analysis of the logical relationship between the fault immediately applied to the 6 factors, quantitatively calculates the probability caused by various factors of the accident immediately brake application.The influence degree of the immediate gate accident was calculated, namely the importance degree, and the important probability was sorted according to the size. It provided the data basis for quickly finding the fault location, and also provided a scientific reference for the design modification of the system.
