摘　　要：文章分析了矿井提升监控系统可靠性问题,通过对淮南潘一煤矿主副井的研究,建立了完整的故障树模型;基于该故障树,通过定性方法得出系统故障的最小割集,通过定量方法得出系统运行50 000h的可靠度;分析得出信号系统和控制系统的可靠度较低,提出对薄弱环节优化设计的方案,以保证系统整体高可靠性的要求。The reliability of mine hoister monitoring system is analyzed and a complete fault tree analysis（FTA） model is built based on the research on main and auxiliary shafts in Panyi coal mine. Based on this FTA, the minimal cut sets are obtained by qualitative method and the reliability of the system after 50 000 running hours is obtained by quantitative method. The conclusion is drawn that the reliability of signal system and control system is lower, and the weak points are optimized in order to meet the high reliability requirement of whole system.
