煤與瓦斯突出預測層次分析-模糊綜合評判方法

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

  • 摘要: 將層次分析和模糊綜合評判方法結合起來應用于煤與瓦斯突出預測研究中.運用層次分析法確定了煤與瓦斯突出各影響因素權重系數,采用隸屬函數構造了單因素判別矩陣,并運用模糊綜合評判法建立了煤與瓦斯突出預測模型.對平頂山研究區典型工作面進行了瓦斯突出危險性的定量預測和突出等級劃分.結果表明,應用層次分析-模糊綜合評判方法預測煤與瓦斯突出強度是可行的.

     

    Abstract: 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.
