摘　　要：针对丘陵山区复杂的地质情况,构建了矿山地质环境影响程度的模糊综合评判指标体系;并引入弱模糊一致矩阵结合层次分析法确定权重,解决了传统AHP很难满足一致性检验的问题;依据矿山特殊地质条件,将地质环境影响程度划分为三个等级构建模糊综合评判表,确定各影响因子的隶属度;运用模糊综合评判方法,建立矿山地质环境影响程度的二级模糊综合评判模型。通过该模型在实际矿山中的应用,模型评估结果与实际结果显示的滑坡、地面沉降等地质灾害影响程度吻合性较高。Based on the complex geological environment and hydro-geological conditions in mountainous areas the fuzzy comprehensive evaluation index system of the mine geological environment is constructed. It uses the weak fuzzy consistent matrix and analytic hierarchy process to calculate the weight, which solves the question that traditional AHP is difficult to meet the consistency test. According to the special geological conditions of the mine, it divides the impact of the geological environment into three levels, builts the fuzzy comprehensive evaluation table and determines the membership degree of the influencing factors. Combined with fuzzy comprehensive evaluation method, it developes a second-order fuzzy comprehensive evaluation model of the impact of the mine geological environment. By means of the application of this model to the actual mining, it shows that the evaluation results of the model are highly similar to the actual results of the impacts of landslides, land subsidence and other geological disasters.
