摘　　要：根据某矿区现场踏勘,结合工程地质条件,针对存在的矿山地质环境问题,总结了影响边坡稳定性的主要因素,研究边坡变形机理,推测矿区边坡未来变形范围。通过调查矿区内博物馆—速凝剂厂范围内塌陷区和博物馆西侧的滑坡,阐述了引起矿山地质环境问题主要因素,即内在因素是边坡自身问题,外在因素是长期震动和堆载。并结合矿区地质环境问题和影响因素,分析了边坡变形机理,将边坡变形分为4个阶段,即孕育阶段、张拉阶段、剪切阶段和滑移阶段。且基于边坡变形机理,推测了滑坡变形范围,大范围的边坡滑移还不存在,仍处于前2阶段。最后,在此基础上,提出了矿山地质环境的治理措施,使边坡稳定问题得以解决。因此,研究采空区上覆岩质高边坡变形机理具有重要的工程意义。According to field reconnaissance and geo-environmental problems in the mining area, the main factors affecting the slope stability are summarized, the slope deformation mechanism is analyzed, and the future deforma- tion range is predicted. Through investigating the subsidence area within the mine museum-accelerator factory and the landslides on the west side of the museum, main factors causing the geo-environmental problems in the mining area are analyzed. The intrinsic factor is the own features of the slope and the external factors are long-term vibra- tion and heaped load. On this basis, the slope deformation mechanism is analyzed, and slope deformation is divid- ed into the following four phases： nurturing, tensioning, shearing and sliding. Furthermore, the future landslide deformation range is predicted, which shows that there＇ s no wide range sliding and the deformation is still in the first two phases. Finally, control measures are proposed to ensure the slope stability.
