Abstract
Non-electric detonator was developed to improve the blasting efficiency of electric detonator. It is increasingly utilized in surface and tunnel blasting due to its safety in external electric shock, precise delayed time, and decrease in blasting vibration and noise. The paper describes the detonating system of non-electric detonator, principle operating and planning methods, and case history so that it can be contributed to improve blasting technology.
