基于三角模糊数的矿井火灾事故树分析

利用事故树分析法对矿井火灾进行分析,结合平煤六矿建立了矿井火灾事故树.应用模糊重要度法对事故树基本事件进行排序,把导致火灾的两大因素进行模糊分级.从模糊概率排序以及分级可以看出,引燃火源和可燃物是比较危险的因素,发生的概率比较大.要想从根本上杜绝火灾,就要严格管理这两个重要的因素.这对于煤矿决策管理有着较重要的意义.

Fault tree analysis of mining fire occurence based on triangle fuzzy numerals

With the fault tree analysis method, the paper analyses mining fire accidents to set up a mine fire fault tree according to the (No.6) Mine of Ping Ding Shan Coal Industrial Group, Henan. The paper also elaborates a theory of fuzzy mathematics and its application in coal mine production. As is known, fuzzy method has been found more and more extensive applications to the order of the basic events in fault tree and fuzzy mathematics analysis tin finding the two factors leading to the coal-mine fire. Thus, it can be seen from the fuzzy probability order and classification that fire source and inflammable matter is comparably dangerous factors, for the occurrence of the fire probability is rather high. So the decision-makers are expected to learn to manage the above two factors strictly if they want to put an end to fire rather high, which contributes to the increase of the sensibility cognition of the mining safety workers to acquaint decision-maker with of these two great factors. Such qualities are very important and valuable to the colliery management.
