| Abstract: |
| In order to verify the effect of anchoring and grouting reinforcement to broken pillars in Tongkeng mine, the reinforcement process is analyzed by numerical simulation with FLAC3D numerical analysis software. It was shown that the plastic region and displacement of surrounding rock obviously decreased after anchoring and grouting . Pillars stability can be significantly improved by the reinforcement of anchoring and grouting. |
