Abstract
In case of urban blasting works at near neighbors, the size of one blasting should be minimized to reduce the vibration and noise. However, the complaints is not decreased due to increased numbers of blasting per day so that the period of blasting works become long. This case study is related to urban apartment construction site. In order to overcome the weakness of general detonators which is required many blasting times to meet the day productivity, we have been applied deck-charge blasting method using electronic detonators and then we successfully increased the day productivity with much less blasting times. Hence, we had effectively achieved the declined neighbors'complaints and shortening construction period.
