我国的煤矿瓦斯事故频发,不仅造成了巨大的经济损失还产生了不良的社会影响。煤矿瓦斯事故的发生并不是单一因素作用的结果,而是源于多种因素相互作用、相互影响。这就要求在进行煤矿安全评价时不仅要系统分析煤矿瓦斯事故发生机理,还要综素之间合分析煤矿系统各因的耦合作用。在借鉴前人研究成果的基础上,利用改进的模糊DEMATEL模型,对煤矿系统多因素之间的耦合作用强度进行了度量,并绘制瓦斯事故的原因-结果图对瓦斯事故进行分析,为分类管理煤矿瓦斯事故危险源提供了科学依据。
The frequent occurrence of gas accidents in coal mines in our country not only caused huge economic losses but also had adverse social impacts. The occurrence of coal mine gas accidents is not the result of a single factor, but from a variety of factors interact with each other. This requires not only to systematically analyze the mechanism of coal mine gas accidents, but also to analyze the coupling effects of all factors in the coal mine system during coal mine safety assessment. Based on the research results of predecessors, this paper uses the improved fuzzy DEMATEL model to measure the intensity of the coupling effect among multiple factors in the coal mine system and draws up the reason of the gas accident - the result map analyzes the gas accident and provides the basis for classification management Coal mine gas accident hazard provides a scientific basis.
