| 摘 要： | 在边坡下采煤,井工开采不仅使边坡岩土体结构发生破坏,物理力学强度降低,同时还会引起边坡岩土体中的应力发生重分布,对露天边坡的变形及稳定性将产生较大影响.本文以山西平朔安太堡露天矿东帮边坡在B900工作面井采影响下的位移监测资料为基础,分析总结了露井联合开采条件下边坡变形规律及机理,并结合结构面组合判断、FLAC数值模拟...

| Abstract: | Underground mining under slope can not only cause that the construction of rock mass is destructed and the mechanical properties are reduced,but also lead to that the state of stress is redistributed and affect the deformation and stability of slope greatly.This paper takes the underground mining of B900 under the east slope of the Antaibao open mine as example.Based on the deformation monitoring data,the deformation law and mechanism are summarized.The stability of slope is estimated by the method of stere... |
