| Abstract: |
| The stability of a mining in an underground mine in Yunnan province, use FLAC3D modeling and simulation of excavation and Select the elevation 3556 ~ 3557m to set up the mining model. The structure parameters of 30 m 14 m and 15 m respectively were simulated for the length, width and height of the stope, and the displacement of excavation area should be calculated and the displacement monitoring of the top bottom plate should be obtained, after using the Monte Carlo method to set up limit equation of numerical simulation in Matlab, it is concluded that the roof and floor and slope failure probability.The failure probability of the left hand side and the right side of the stope are relatively small, while the failure probability of the top plate is relatively large. |
