摘　　要：为有效开展沉陷灾害防治措施,确保煤矿安全有序生产,将模糊层次分析法引入到沉陷灾害评价中,构建了黄土沟壑区沉陷灾害综合评价模型。该模型首先根据层次分析法确定各评价因子的权重,然后通过隶属度函数进行模糊综合评判,最终根据最大隶属度原则,对矿区沉陷灾害进行整体综合评价,获得合理可靠的评价结果。该方法以层次分析法确定权重,以模糊综合评判法选取合理的隶属度函数,综合考虑多因素、多层次的影响,使评价结果更加科学。采用所建立的模型对内蒙古某井工煤矿工作面进行综合评价,计算结果和矿区实际危险性情况吻合。应用表明,所建立的模糊层次分析法考虑了断裂活动、开采高度和地裂缝宽度等因素,并采用模糊综合评价对评价因子进行定量化处理以提高评价结果的准确性,在类似黄土沟壑煤矿区开采地表沉陷灾害评价研究中有推广应用价值。In order to carry out the prevention and control measures of subsidence disaster and ensure the safe effectively and production of coal mine orderly,the fuzzy analytic hierarchy process(FAHP)was introduced into the subsidence disaster evaluation,and the comprehensive evaluation model of subsidence disaster in loess gully region was constructed.The model first determines the weights of each evaluation factor based on the Analytic Hierarchy Process,and then conducts fuzzy comprehensive evaluation through the membership function.Finally,according to the principle of maximum membership,the overall comprehensive evaluation of mining subsidence disasters is carried out to obtain reasonable and reliable evaluation results.The method uses AHP to determine the weight,fuzzy comprehensive evaluation method to select a reasonable membership function,and comprehensively considers the influence of multiple factors and levels,making the evaluation results more scientific.The model was used to evaluate the working face of a coal mine comprehensively in Inner Mongolia,and the calculated results are consistent with the actual risk situation of the mine.The application shows that the established fuzzy analytic hierarchy process takes into account factors such as fault activity,mining height,and ground fissure width,and uses fuzzy comprehensive evaluation to quantitatively process the evaluation factors to improve the accuracy of the evaluation results.It has promotion and application value in the evaluation of surface subsidence disasters in mining areas similar to loess gully coal mines.
