| Abstract: | Digital detonator is one of most advanced blasting cap in the world,and its elements for delaying time are different from those of electric detonator and Nonel detonator.Digital detonator with accurate delaying time is effective tool in decreasing blasting vibration velocity of blasting engineering.Based on construction of Niuwanggai tunnel in Guiyang-Guangzhou high speed railway,many trials of decreasing blasting vibration velocity were carried out using digital detonator and Nonel detonator.The results indicated that blasting vibration velocity could be reduced about 60%80% by using digital detonator.Digital detonator provided effective technology for resolving safety problems caused excavation tunnel by drill-blasting in complicated surroundings. |
