【摘要】：通過分析與煤礦瓦斯爆炸相關(guān)的危險源,將Petri網(wǎng)理論與瓦斯爆炸演變過程結(jié)合起來,構(gòu)建了基于Petri網(wǎng)的瓦斯爆炸演變模型GEFRPN,并得出了如下結(jié)論:從瓦斯爆炸演變模型的推理過程可以很清楚地看到瓦斯爆炸演變過程中各個危險源可信度的變化,從而得出各個危險源在瓦斯爆炸演變過程中所起的作用大小;由推理結(jié)果以及Petri網(wǎng)圖可分析危險源對瓦斯爆炸的重要度,以便及早采取措施,避免瓦斯爆炸事故發(fā)生;瓦斯爆炸演變模型引入了置信度,演算結(jié)果具有模糊性,克服了事故樹方法所得結(jié)果與實際情況有一定出入的不足。
[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.
