摘要/Abstract

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。

Abstract: 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 deformation 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 vibration and heaped load. On this basis, the slope deformation mechanism is analyzed, and slope deformation is divided 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.

Key words: goaf, high rock slope, geo-environmental problems of mine, deformation mechanism
