The results show that the dominant frequency componems of single deck blast vibration signals are concentrated at the higher frequency band(39 Hz-156Hz)and the ratio of the energy of low frequency components(less than 39 Hz) to the total energy is lower.

• 结果表明,在单段爆破中,爆破震动信号成分主要以中高频(39Hz~156Hz)为主,低频成分(39Hz以下)所占比例极少。
