Abstract
An electronic initiation system that can support various types of field blasting works has been developed and put into practice. The newly developed equipment called Hanwha Electronic Blasting System (HEBS) II has three basic operation modes of scanning, logging, and tagging, among which the blaster can choose the most suitable one for the specific site conditions. In the present study, the work efficiency of the system in the scanning, logging and tagging modes was compared with that of the previous non-electric detonator. The results were estimated based on the aspects of the ground vibration, fragmentation, and digging time. It was found that the ground vibration, fragmentation, and digging time of the new system were decreased by about 45%, 31%, and 13%, respectively, with respect to the previous system. This result confirms that the new system is very efficient in the scanning, logging and tagging modes under the field conditions.
