摘　　要：在分析煤矿井下连续运输系统结构、运行特征的基础上,应用随机Petri网理论构建煤矿井下连续运输系统SPN模型,实现了系统部件故障维修过程的动态描述。同时,结合马尔科夫方法对某煤矿井下连续运输系统进行可靠性分析,计算得出其系统有效度和不可用度。该研究为分析煤矿井下连续运输系统可靠性提供新的思路。Based on the analysis of the structure and operating characteristics of the underground coal mine continuous transportation system,the stochastic Petri net theory was used to construct the SPN model of the underground coal mine continuous transportation system, and the dynamic description of the system′s fault maintenance process was realized. At the same time,combined with the Markov method,the reliability analysis of the underground continuous transportation system in a coal mine was carried out,the system effectiveness and unavailability were calculated. This research provides new ideas for analyzing the reliability of underground continuous transportation systems in coal mine.
