Numerical Simulation Analysis of Underground Stoping Sequence in Jinchangyu Gold Mine |
| |
Abstract: | In the undergroud stoping of Jinch-angyu,the stope stability is obviously affected by the different stoping sequence.The stoping sequence is systematically studied by using ANSYS and3-D elastoplastic finite element analysis to get optimum stoping sequence,whi-ch makes the damage extent and scale of pillar smallest and insures the safety of stope. |

Keywords: | stoping sequence stope stability ANSYS elastoplastic finite element |
