| Abstract: | Based on the present state of upward sector medium - deep hole blasting in dahongshan copper mine, the effect of joint and crack on medium - deep hole blasting are studied via theoretical analysis and indoor modeling test, the blasting structural parame- ters are optimized by combining test conditions with site practice. The application practice shows that the blasting effect is good after parameters optimization, the oversize block ratio is decreased and the ore production efficiency is increased. |
