基于模糊综合评价的瓦斯突出危险性分析

Fuzzy comprehensive evaluation of the safety for gas outburst

针对煤矿瓦斯突出的问题,依据煤与瓦斯突出的相关理论及其影响因素,应用模糊综合评价法建立了突出危险评价指标体系,对影响煤与瓦斯突出的各个因素综合分析并对指标体系进行多级评价,最终得出矿井煤与瓦斯突出危险性的定量评价结果.以唐山马家沟煤矿为例,详细分析了各个指标,构造了判断矩阵及相对权重,建立了评判集进行评价,准确全面地反映了综合情况,为煤矿瓦斯事故危险源安全现状的综合评价提供了合理途径.

Focusing on the gas outburst problem,a prominent risk evaluation index system is established based on the coal and gas outburst theory and the related factors and using the fuzzy evaluation method. The comprehensive analysis of each factor is made,and the evaluation is done,the quantified evaluation of gas outburst danger is achieved. With the Tangshan Majiagou Coal as an example,detailed analysis of the various indicators is conducted and the construction of fuzzy matrix and weights are give,the evaluation set is achieved. The evaluation correctly and totally reflected the real situation,applying a reasonable way to evaluate the real situation of gas outburst and the dangerous sources.
