| Abstract: | A millisecond detonator is introduced in this paper.This detonator,a stantaneous electric detonator,is ignited through the built-in electronic circuit which produces a certain delay and energy pulse current.So the stantaneous detonator can replace millisecond detonator in millisecond blasting in open pits and underground mines. |
