煤矿瓦斯爆炸事故演化危险性评价的AHP-GT模型及应用

分析了传统瓦斯危险性评价方法与模型存在的问题，通过对煤矿瓦斯爆炸“人-机-环境-管理”复杂非线性系统分析，建立生产人员素质因素、生产装备因素、环境条件因素、安全管理因素等4个大类和27个小类的危险性评价指标体系。在层次分析法和灰色聚类法等研究基础上，构建了煤矿瓦斯爆炸事故演化危险性评价的非线性多层次灰色评价模型(AHP-GT)，确定了评价模型中评价灰类的等级数、灰数及白化权函数，根据评价灰类及白化权函数的非线性，修订了评价目标综合评价等级标准。给出了评价实例，评价结果符合实际。

Research and Application of AHP-GT Model of Gas Explosion Accident Evolution Risk Assessment in Coal Mine

Risk assessment of gas explosion accident evolution in coal mine is to implement "Safety first, Prevention primary", and to improve the essential safety and safety management, and to prevent and control gas explosion accidents. The problems of traditional risk assessment model of gas explosion were analysis. Based on "human - machine - environment - Management" complex non-linear system, the risk assessment index system about four major categories and 27 sub-categories include the quality of factors of production personnel and the production equipment factors and the environmental conditions factors and the safety management factors was established. The non-linear multilevel gray evaluation model (AHP-GT) of risk assessment of gas explosion accident evolution in coal mine was established based on AHP and gray clustering method. The risk assessment grade and the gray type and whitening weight function were classified and defined. The evaluation of objective comprehensive evaluation rating criteria was amended according to the nonlinear of whitening weight function. The risk assessment example was give and the results conform to reality.
