围岩稳定性模糊综合评价方法的研究与应用

Research and Application on Fuzzy Comprehensive Evaluation of Surrounding Rock Stability

在对围岩稳定性进行评价时,结合不同的围岩分类方法,根据评价参数实验值给出各参数围岩稳定性分级的可信度,并建立评价矩阵,利用层次分析法确定各评价指标的权重,通过矩阵运算实现对围岩稳定性的综合评价。该模型被应用到鸡西矿业集团生产实践中,取得了很好的效果。

When this method is utilized to evaluate the stability of surrounding rock, combining with the different surrounding rocks categorization, the credence levels the stability of surrounding rock determined according to the tested values of different evaluation parameters is used to construct an evaluation matrix, and analytic hierarchy process method is used to determine the weights of evaluation indexes, tinally, stability of surrounding rock is evaluate by the matrix multiplication calculation. The established model has been applied in production practice in Jixi Mining Industry Group, and better results have been obtaine.
