摘要
Abstract
The vibration monitoring was conducted by setting different measurement points for a series of millisecond blasting to study the blasting vibration under different initiation sequence. The corresponding data regression and wavelet packet analysis show that the maximum vibration intensity is along the reverse direction of blasting throwing, which changes with the blasting sequence. The blasting seismic wave frequency in the different directions and frequency band energy distribution of vibration signal have some regularity; The proportion of blasting vibration within 15Hz band in blasting throwing reverse direction is obviously higher than in the other directions, and the blasting seismic wave in throwing reverse direction has the larger harm on the surrounding structures.关键词
