암반굴착에 따른 발파진동과 브레이커진동의 특성에 관한 연구
A Study on the Characteristics of Blasting Vibration and Breaker Vibration by Rock Excavation
초록
The blast works for open cuts and underground constructions near urban areas have recently increased complaint of ground vibration, air blast and fly rock. In order to reduce these problems, it is necessary to develop more cautious blasting, or non-blast excavation methods by mechanical power. For these breaker workings instead of blast are sometimes adopted. To compare the characteristics of blast vibration with breaker vibration, the level, range of frequency and spectrum amplifications of each vibration were studied.
