| Abstract: |
| 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和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. |
