| Abstract: | Analysis & research are made about the feature of blasting stress field formation in the case of segmental blasting holes with column loading and hole|bottom detonation,about the stress waves overlap and about the dynamic change of stress field,Thus the mechanism of rock breaking by blasting is theoretically cleared.Based on results of this analysis & research,technological measures mines should take in the practice are introduced. |
