Abstract

The delay precision of common detonator is not good, the actual time delay often have big difference with blasting design in real blasting engineering, and the blasting effect is difficult to control. While high precision digital detonators are instead of chemical drugs by original electronic control chip, so it has very high precision delay, and it is widely used in reducing blasting vibration and improving blasting effect. According to the contrast analysis of blasting vibration generated by digital electronic detonator and common detonator in actual situation, the total energy ratio of energy and D7 band ratio is regarded as index. Comparing results of the vibration reduction effect of digital detonator with common detonator proves that digital detonator in reducing blasting vibration effect is on superiority. It is worth to be promoted.
