摘要
瓦斯爆燃是矿井火灾的诱发因素之一,由于瓦斯特殊的物理化学性质和赋存条件导致其爆燃形式与煤自燃有许多不同之处.从瓦斯爆燃的三要素入手,结合综放面瓦斯爆燃事故的特点,建立了基于瓦斯爆燃的火灾事故树,在基本事件概率不清楚的情况下,应用模糊数学理论将基本事件概率看作L-R模糊数,对事故树分析得出各个事件的概率值,为矿井防火提供更加科学的参考依据.
Gas Combustion is one of the factors that cause mine fire. Because of the physical and chemical properties of gas, there are many differences between gas combustion and coal spontaneous combustion. By analyzing the three elements of the Gas Combustion, combining the characteristics of the gas combustion of fully mechanized coal mining face, the article builds the fault tree of mine gas combustion fire. When the bas- ic events of fault tree is ambiguous, through application of fuzzy mathematical theory, probability of basic vari- ous events is taken as a L - R fuzzy number. And the probability of various events can be gotten. The paper provides more credible reference for mine fire prevention.
