煤矿瓦斯爆炸风险的模糊数学评价

摘要

将模糊数学评价法运用于煤矿瓦斯爆炸灾难危害评价中，从第一类危险源、第二类危险源、第三类危险源的视角钻研，分析了对煤矿瓦斯爆炸影响主--素，以白山坪煤矿采煤工作面瓦斯涌出的实际情况为例，进行了瓦斯爆炸灾难危害评价，得出了白山坪煤矿3个采煤工作面瓦斯爆炸风险顺序为1267＜1263＜1265，验证了模糊数学评价运用于煤矿瓦斯爆炸危害评价的合理性。针对1267工作面没有达到“一般安全”的实际情况，提出了防治瓦斯爆炸事故的一些措施。%This paper applies the fuzzy mathematics evaluation method to the evaluation of coal mine gas explosion disaster and harm.From the perspectives of the first risk sources,the second ones,and the third ones, this paper analyzes the main factors that affect coal mine gas explosion.According to the actual situations of Baishanping Coal Mine’s coal working face gas emission for the gas explosion disaster evaluation,it gets the 3 coal working face’s risk order of gas explosion in Baishanping Coal Mine,that is 1267 <1263 <1265,which verifies the rationality of fuzzy mathematics evaluation method used in coal mine gas explosion hazard evaluation. In light with the 1267 working face which does not meet the “general safety”,this paper puts forward some measures for preventing gas explosion from happening.
