针对煤与瓦斯突出预测缺乏定量评价方法,将层次分析与模糊综合评判运用到煤与瓦斯突出危险程度预测中,使用层次分析法确定了煤与瓦斯突出各影响因素权重系数,运用模糊综合评判法建立了煤与瓦斯突出危险程度预测模型。最后,对某煤矿9煤层进行了煤与瓦斯突出危险性预测。结果表明,应用层次分析与模糊综合评判进行煤与瓦斯突出危险程度预测是可行的。
Aiming at the lack of quantitative evaluation methods for coal and gas outburst prediction, the paper applies AHP and fuzzy comprehensive evaluation to the prediction of coal and gas outburst danger degree, and uses the analytic hierarchy process to determine the weight coefficient of various influencing factors of coal and gas outburst. By using fuzzy comprehensive evaluation The prediction model of dangerous degree of coal and gas outburst was established. Finally, coal and gas outburst danger prediction is carried out for 9 coal seam in a coal mine. The results show that the application of AHP and fuzzy comprehensive evaluation of coal and gas outburst danger degree is feasible.
