基于AHP及模糊综合评判法的采空区稳定性评价

以石人沟铁矿为工程背景，结合石人沟铁矿采空区的实际情况，采用模糊综合评判法，建立了含有15个评价因子的二级模糊综合评判模型。通过专家打分法对定性因子进行评价，采用三相线性隶属函数对定量因子进行评价，确定了模糊评价矩阵。采用层级分析法（AHP）确定因子权重，建立了因子权重集，然后将判断矩阵与因素权重集进行运算，以完成对采空区稳定性的综合评价。研究结果表明：二级模糊综合评判模型得出的评价结果能够较准确地反映采空区的稳定性，是矿山采空区稳定性分析的有效方法和手段。

Stability Evaluation for Mine Gob Areas Based on AHP and Fuzzy Synthetic Judgement Theory

Based on the engineering background of Shi rengou iron mine, according to the practical condition, using multi-stage fuzzy synthetic judgement theory, this paper makes a two-stage fuzzy synthetic judgement model of the stability of mine gob area with 15 factors.The fuzzy evaluation matrix is made using expert evaluation method and three-phase linear membership function method to evaluate the qualitative and quantitative factors.The weight of factors are determined using AHP,then a weight matrix is made.The concourse are then calculated together with the evaluating matrix to complete the synthetic evaluation of gob area stability variable.The results show that the evaluation results can accurately reflect the stability of mine gob area.This is a effective method to analyze the stability of mine gob area.
