Abstract: The characteristics of the electronic detonator and its system are briefly introduced. And the main principle that the digital electronic detonators reduce the vibration by differential in terference is elaborated. Finally, in the engineering case of Guanziling Tunnel, comparing with the blasting effect of the traditional blasting materials, the conclusion is drawn that the electronic detonator has a distinct advantage in economy, safety and vibration reduction

Key words: electronic detonator, tunnel, large section, smooth blasting, pre-split blasting
