摘　　要：针对后山煤矿的具体地质环境和采煤可能引发的地质灾害问题,采用区域调查法和地质环境综合判别法,系统分析了研究区地形地貌、地质构造、水文地质条件等地质环境。根据最大下沉值、影响半径、斜率、曲率和水平变形、最大下沉角、开采影响传播角(α>50°)、冒落带高度值、导水裂隙带高度值等对研究区发生地质灾害的危险性进行了预测研究。研究结果表明:该区地质环境复杂程度为中等复杂,矿山受采矿影响发生地质灾害的可能性大,危险性大。In view of the specific geological environment of the Houshan coal mine and geological disasters potentially caused by mining, the authors used the regional survey and geological environment assessment and analysed the geological environment such as landscapes, geological formations, and hydrogeological conditions systematically. According to the value of maximum sinkage, the radius of influence, slope, rate of curve and the horizontal deformation, angle of maximum subsidence, mining propagation angle（α〉50 degree）, the height value of caving zone, the height value of fissure zone which water can permeate, the risk of geological disasters which may occur in the study area has been predicted. The study shows： the complexity of the geological environment is secondar. The possibility of geological disasters caused by mining is great and the risk. of geological disasters is high.
