摘　　要：本文用Petri网模拟和分析煤矿事故,以煤炭自然发火为例,通过构造事故的Petri网,作出Petri网的可达标识图。分析可达标识图,可求出导致顶上事件发生的最小割集和控制事故发生的最小径集,为选择控制事故的最佳方案,提供了可靠的理论根据。此方法形象、直观,为煤矿安全系统工程及其它事故分析,开辟了一条新的途径。Accidents,for example,spontaneous combustion of coal are simulated and analyzed by a Petri Net in this paper.Reachability identification graphs of the Petri Net are set up based on accident Petri Net,and the minimum cutsets, which lead to accidents and minimum success sets,which control the accidents, can be obtained by analysis of teachability identification graphs. It is a reliable theory for choosing an optimal proposal for controlling the accidents.It is a visual aid.It provides a new approach for system engineering of coal mine safety and for analysis of accidents.
