野外踏勘结果显示平朔矿区因煤炭采掘活动而引发的地质效应点共172个，其中地面塌陷群共17处，边坡不稳定群8处，地裂缝196条，地质效应总面积654.77hm2。层次分析法能够较为准确地判别出地面塌陷影响因素的重要程度，并给出各个因素所占的权重。地面塌陷的影响因素包括人为因素和自然因素。结合平朔矿区的实际情况，选取人为因素（包括采空区规模，采深和采厚，采煤方法和顶板管理方法），自然因素（包括水文地质条件，构造应力，覆岩的结构与硬度煤层倾角，）两类影响因素进行分析。通过层次分析法和一致性检验得出平朔矿区的地面塌陷主要受采深采厚比、采空区规模和覆岩的结构与硬度三个方面控制，权重值分别为0.469、0.188和0.114。由此可以判断，平朔矿区地面塌陷主要控制因素为人为因素，国土资源部门和煤炭生产单位做生产规划时要着重考虑周边煤矿采空区的影响。\n

The field survey results show that there are a total of 172 geological effect points in the Pingshuo mining area caused by coal mining activities, including 17 ground subsidence groups, 8 unstable slope groups, 196 ground fissures, and a total geological effect area of 654.77 hectares. The Analytic Hierarchy Process can accurately determine the importance of factors affecting ground subsidence and provide the weights of each factor. The influencing factors of ground subsidence include human factors and natural factors. Based on the actual situation of Pingshuo mining area, two types of influencing factors are selected for analysis: human factors (including goaf size, mining depth and thickness, coal mining methods and roof management methods) and natural factors (including hydrogeological conditions, structural stress, overlying rock structure and hardness, coal seam dip angle). Through the Analytic Hierarchy Process and consistency testing, it was found that the ground subsidence in Pingshuo mining area is mainly controlled by three aspects: the ratio of mining depth to mining thickness, the scale of goaf, and the structure and hardness of overlying rock, with weight values of 0.469, 0.188, and 0.114, respectively. From this, it can be inferred that the main controlling factor for ground subsidence in Pingshuo mining area is human factors, and the land and resources department and coal production units should pay special attention to the impact of surrounding coal mine goaf when making production planning.\n
\nThe research focuses on the impact of mining progress on open-pit slopes in the open-pit mining area. Using the FLAC3D program, an ideal model for open-pit mining in Pingshuo mining area is established, and the constitutive model is the Mohr Coulomb model. Based on the mechanical parameters of each layer of rock and soil, a model is established, and the simulation results show that under the action of open-pit mining, the slope mainly undergoes settlement deformation. As the mining progresses, a goaf gradually forms.
