基于熵权模糊综合的煤矿瓦斯爆炸危险性评价

Fuzzy Comprehensive Evaluation on Explosion Risk of Coal Mine Gas based on Entropy

煤矿瓦斯爆炸是受多种因素共同影响的复杂过程,而熵权法是根据煤矿瓦斯爆炸事故发生的机理和特征,分析各影响因素之间的相互关系,将主观因素和客观因素综合起来,确定各影响因素的权重,建立起基于熵权和模糊综合的煤矿瓦斯爆炸危险性评价模型,并对某矿瓦斯爆炸危险性进行了评价,结果与实际情况一致,具有一定的实际应用价值。

Coal mine gas explosion is a complex process which is influenced by many factors together.Based on the mechanism and characteristics of coal mine gas explosion accident,the relationship between all influence factors was analyzed by using entropy method.By integrating the subjective and objective factors,confirming the weighing of all influence factors,fuzzy comprehensive coal gas explosion risk evaluation model on the basis of entropy weight was established.The evaluation was done on gas explosion risk of one mine,and the result was consistent with practical situation,had a certain practical using value.
