| Abstract: | Taking the blasting construction of Qipanshan Tunneling of Wuguang High-speed Rail as an example,it is found that the longxin-one digital electronic detonator and iridium bowl initiation system can improve the utilization efficiency of blasting energy effectively,reduce the amount of dynamite and increase the blasting effect at surrounding smooth plane,in contrast with the non-electric blasting construction of millisecond delay detonator.In addition,the former can reduce many secondary disasters,such as damping,noise reduction,etc.In the future,it should have more broad application prospects at tunneling construction. |
