摘要
Abstract
Ground vibration tests at different charge delay intervals were conducted in a small pool to study the impact of underwater delay blasting on the vibration of ground surface. During the experiment, the charge number was various for each group at a constant charge quantity in total. The ground vibration velocities and main frequencies were tested and analyzed by UBOX-5016 blasting vibration recorder. The study shows that millisecond delay blasting can effec-tively reduce the blasting vibration. The reasonable delay interval was preliminarily estimated to be 25-50ms at optimized charge delay interval.关键词
