APPLICATION OF ELECTRONIC DETONATOR IN MOUNTAIN LOOSE BLASTING ENGINEERING
Dongtao Li, Yao Hao-hui · Engineering Blasting · 2012
The application of Lux No.1 electronic detonator in Sichuan Guangyuan Dazhongba Mountain loose blasting engineering was introduced.The reasonable delay time of it was chosen through the engineering practice so as to reach the effects of reducing the blasting vibration and increasing blasting volume. In blasting trial process,the blasting vibration maximum was eventually controlled between 0.41 and 0.65 cm/s by blasting vibration monitoring and was 30%of using Nonel blasting,and single excavation volume was improved four times.Effects of reducing blasting vibration were obvious,and the construction progress was effectively sped up,which brought significant economic and social benefits for the engineering.
