摘要
本文从地质环境条件、采矿工程活动两个主要因素着手进行综合分析,选取影响城郊煤矿地面采空塌陷的9个因子,采用模糊综合评价的方法对城郊煤矿地面塌陷危险性进行评价,确定隶属函数,构建模糊评价矩阵,并利用层次分析法确定各影响因子权重,建立矿区地面塌陷危险性评价模型并将矿区地面塌陷危险性程度划分为危险性小区、危险性中等区以及危险性大区3个等级。结果表明,该评价模型能较好地应用于城郊煤矿地面塌陷危险性评价中,该评价方法是实用和有效的。
In this paper,nine factors,which affect the subsidence of subsurface collapse,are obtained from the two main factors of geological environment and mining engineering activities. The fuzzy comprehensive evaluation method is used to evaluate the ground collapse risk of suburban coal mine,determine the membership function and construct a fuzzy evaluation matrix,and the weight of evaluation factor is determined by analytic hierarchy process. The risk assessment model is established,and the mining area is divided into three types: large risk,medium risk and low risk. This method objectively empowers people and reduces subjective criticism. Studies have shown that the evaluation model can be applied to the risk assessment of ground subsidence in suburban coal mines. The evaluation method is practical and effective.
