【摘要】:通过分析与煤矿瓦斯爆炸相关的危险源,将Petri网理论与瓦斯爆炸演变过程结合起来,构建了基于Petri网的瓦斯爆炸演变模型GEFRPN,并得出了如下结论:从瓦斯爆炸演变模型的推理过程可以很清楚地看到瓦斯爆炸演变过程中各个危险源可信度的变化,从而得出各个危险源在瓦斯爆炸演变过程中所起的作用大小;由推理结果以及Petri网图可分析危险源对瓦斯爆炸的重要度,以便及早采取措施,避免瓦斯爆炸事故发生;瓦斯爆炸演变模型引入了置信度,演算结果具有模糊性,克服了事故树方法所得结果与实际情况有一定出入的不足。
[Abstract]:By analyzing the dangerous sources related to gas explosion in coal mine, the theory of Petri net is combined with the evolution process of gas explosion. A gas explosion evolution model GEFRPN based on Petri net is constructed, and the following conclusions are drawn: from the inference process of gas explosion evolution model, we can clearly see the changes of the credibility of each dangerous source during the evolution of gas explosion. From the result of reasoning and Petri net diagram, the importance of dangerous source to gas explosion can be analyzed in order to take early measures to avoid gas explosion accident. Confidence degree is introduced into the evolution model of gas explosion, and the result of calculation is fuzzy, which overcomes the deficiency that the result obtained by the accident tree method has some discrepancy with the actual situation.
