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. In view of the danger of coal mine gas disaster and its explosion and the mechanism and conditions of the explosion caused by gas explosion, a risk assessment index system is established from four aspects of human-machine (object) -Environment-management, combining with gray theory and interval analytic hierarchy process, The coal mine gas explosion hazard coupling evaluation model is established.I IAHP is used to determine the index weight of the evaluation model and the central point trigonometric whitening weight function is introduced to improve the traditional whitening weight function with gray crossover phenomenon.According to the intrinsic properties of the model index, , And puts forward the evaluation method of coal mine gas explosion risk based on gray-IAHP.The practical evaluation test of 5 working faces in coal mine is carried out by using this evaluation method.The results show that: The gas explosion risk is safer, the result is consistent with the actual situation in the coal mines, indicating that the evaluation model has good reliability and feasibility.
