摘要
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 judgment 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.
