煤与瓦斯突出预测层次分析-模糊综合评判方法

Prediction method of coal and gas outburst by analytic hierarchy process and fuzzy comprehensive evaluation

将层次分析和模糊综合评判方法结合起来应用于煤与瓦斯突出预测研究中.运用层次分析法确定了煤与瓦斯突出各影响因素权重系数,采用隶属函数构造了单因素判别矩阵,并运用模糊综合评判法建立了煤与瓦斯突出预测模型.对平顶山研究区典型工作面进行了瓦斯突出危险性的定量预测和突出等级划分.结果表明,应用层次分析-模糊综合评判方法预测煤与瓦斯突出强度是可行的.

The prediction of coal and gas outburst was studied by analytic hierarchy process （AHP） and fuzzy comprehensive evaluation. In the prediction method, AHP was applied to confirm the weights of coal and gas outburst factors, the iudgment matrix of each factor was constructed by membership functions, and the prediction model of coal and gas outburst was established by the fuzzy comprehensive evaluation method. The prediction method was applied in risk type areas to forecast the coal and gas outburst quantitative intensity and the risk grade was divided in Pingdingshan typical mining area. The results show that the hierarchy process and fuzzy comprehensive evaluation method was available for forecasting the coal and gas outburst intensity.
