| Abstract: | Based on the engineering design of turning open-pit into underground mining in the Nanfen Iron Mine,a section model is established,and the influence of underground mining on the slope stability is numerically simulated by using the finite difference software FLAC.According to simulated distributions of displacement field and stress field of the Nanfen Open-pit slope during underground mining process,some possible unstable parts in the slope are pointed out.And a number of proposals related with the mine production are put forward,which can provide references for safety production. |
| Keywords: | Nanfen Iron Mine turning open-pit into underground mining slope stability FLAC software numerical simulation |
