| Abstract: | Electronic detonator is one of the most advanced blasting caps in the world. Its High precision and controllability of delay provide a strong support to decrease blasting vibration velocity in three ways, namely control of maximum single blow blasting charge and stagger of peak of wave and interference of wave. Based on the pillar recovery mining work, many experiments of blasting vibration velocity decreasing were carried out using electronic detonator. The test results show that the blasting vibration velocity is within the national standard specification. Electronic detonator provided effective technology for resolving safety problems caused by pillar recovery. |
