| Abstract: |
| The mining and supporting roof with long-anchor cable process of an industrial test stope in Anqing Copper Mine is simulated by using nonlinear large deformation FLAC^3D numerical analysis software. Effecting of long-anchor cable reinforcing on stope roof stability is studied. The numerical results show that plastic region and displacement of roof mass are obviously diminished after loaded long-anchor cable, reinforcement using long-anchor cable technique can improve stope roof mass stability. |
