【摘要】：针对煤矿瓦斯灾害及其爆炸的危险性,利用斯爆炸致灾机理与条件,从人-机(物)-环境-管理4个方面建立危险性评价指标体系,结合灰色理论与区间层次分析法,建立煤矿瓦斯爆炸危险性耦合评价模型.通过IAHP确定评价模型指标权重,同时采用中心点三角白化权函数引入改进传统白化权函数存在灰类多重交叉现象;根据模型指标的固有属性不同,采用相就的评价方法以及相对应的评价等级划分,提出基于灰色-IAHP的煤矿瓦斯爆炸危险性评价方法;运用该评价方法对煤矿现场5个工作面进行实践评价检验.研究结果表明:5个工作面的瓦斯爆炸危险性均为较安全,结果与煤矿的实际情况一致,表明该评价模型有较好的可靠性与可行性.
[Abstract]:In view of the hazard of gas disaster and explosion in coal mine, the hazard assessment index system is established from the four aspects of human-machine (material-environment) management, combining grey theory and interval analytic hierarchy process (AHP), using the mechanism and condition of gas explosion caused by Si explosion. The coupling evaluation model of coal mine gas explosion hazard is established. The index weight of evaluation model is determined by IAHP, and the grey multiple cross phenomenon is found by introducing the center point triangle whitening weight function into the improved traditional whitening weight function. According to the different inherent attributes of the model index, a method of coal mine gas explosion risk assessment based on gray IAHP is proposed by adopting the evaluation method and corresponding evaluation grade. The method is applied to the practical evaluation of 5 coal mine working faces. The results show that the gas explosion hazard in all the five working faces is relatively safe, and the results are consistent with the actual situation of the coal mines. It shows that the evaluation model has good reliability and feasibility.
