摘要
针对冲击矿压各个因素的影响程度,利用模糊数学综合评判和层次分析法相结合的方式,根据冲击矿压震级强度和抛出的煤量以及专家和现场工作人员对单因素的评价确定出的隶属度,建立了关于预测冲击矿压的数学模型,并利用层次分析法确定出评价指标的权重,最后通过综合评判的方法预测出发生冲击矿压的危险等级。
According to influence degree of each factors on impulsion pressure,using forms of fuzzy mathematics comprehensive evalution and analytic hierarchy process,base on the magnitude strength of impulsion pressure and outburst coal,experts and field staffs determine the membership about the single factor evaluation,sets up a mathematical model of impulsion pressure and using analytic hierarchy process calculates the weight of evaluation index,predicts the risk grade of impulsion pressure by comprehensive evaluation.
