Abstract
A drill & blasting method using explosives is the most efficient way to break the rock in the urban projects. However, the blasting method cause vibration, noise and fly-rock as blast pollutions so that blasting wroks are restricted by adjacent structures such as apartment and residence houses. To conduct blasting works at near structures, the numbers of blast-holes a blast and the size of the blast are limited by kinds of detonators and initiation methods. So, the production rate is reduced and the construction period should be increased. Therefore, in this case the deck-charge blasting methods using available detonators in domestic market were designed and evaluated in order to confirm the application possibilities in specific urban sites.
