为了更合理地确定影响煤与瓦斯突出因素的权重,在层次分析法判断矩阵的构造上,论文主要用三标度法对传统的九标度法进行改进。利用改进的层次分析法确定影响煤与瓦斯突出各因素的权重,用隶属度构造了单因素模糊判别矩阵,用模糊综合评判建立了预测煤与瓦斯突出的多种模型,并且进行了二级模糊综合评判。将改进的层次分析法和二级模糊综合评判结合起来应用于煤与瓦斯突出危险等级预测中。对神仙坡等煤矿的多个工作面进行了煤与瓦斯突出危险等级预测。结果表明,利用改进的层次分析法——二级模糊综合评判预测煤与瓦斯突出等级是合理可行的,可以较准确地进行等级预测。
The paper intends to improve the traditional Nine-scale method with the Three-scale Method on the basis of the Analytic Hierarch Process(AHP) judging matrix to reasonably determine the weights influencing coal and gas outburst.The improved one has the following advantages: the AHP is to make certain the weights influencing coal and gas outburst;the single-factor fuzzy judging matrix is constructed by the degree of membership;the prediction models of coal and gas outburst is established by fuzzy comprehensive evaluation;the secondary fuzzy comprehensive evaluation is carried out.The improved Analytic Hierarch Process and secondary fuzzy comprehensive evaluation method are used to predict the degree of coal and gas outburst.Such working faces as the Fairy Slope Coal Mine′s are predicted and it turns out that the improved AHP and secondary fuzzy comprehensive evaluation method are reasonable and feasible to predict the coal and gas outburst of different degrees.
