| Abstract: |
| VCR with precision drilling is a new mining technology based on the bundle-hole spherical charge blasting.In this paper,the stress states of mine rock with different mining stages using VCR method are analyzed by a 3-D numerical analysis software.The results can provide reference for the mining design. |
