中文摘要：
根据结构面与边坡面间的组合关系及地下矿体开采影响程度的不同,将边坡岩体分为Ⅰ、Ⅱ、Ⅲ和Ⅳ四个区域,并分析了各个分区边坡岩体的稳定性状态。运用FLAC 3D软件,模拟地下-15m水平开采对边坡应力场、位移场的影响,结果表明受地下开采扰动的影响,研究区域位移沉降明显,下部岩体位移方向指向采空区,易出现塌落破坏以充填地下采空区,上部岩体位移方向沿坡面指向采坑底,易出现牵引式滑动破坏。
英文摘要：
According to the combination relation between structural surface and slope surface,conditions of underground ore body,and so on,the slope rock mass is divided into four different regions（Ⅰ,Ⅱ,Ⅲ,Ⅳ）and the slope stability is analyzed in each region.By FLAC 3D,the stress and displacement field of the slope is simulated during the process of underground mining.The results show displacement subsidence of the study area is affected by underground mining and it is likely cause collapse damage in the lower rock mass and sliding failure in the upper rock mass.
