| 摘 要： | 为研究不同微差间隔下爆破振动信号的反应语特性,基于金堆城露天矿现场爆破振动试验数据,对不同微差间隔的两孔爆破振动信号进行了反应谱分析.首先,利用实测的爆破振动速度信号采用直接微分法获得了加速度信号,并利用EEMD分解时加速度信号进行低通滤波去噪处理,获得了准确清晰的加速度曲线.然后,利用精确法求得了不同微差间隔下爆破振...

| Abstract: | In order to study the response spectrum property of basting vibration signals with different microsecond delay time,basing on monitored data on field blasting vibration in Jinduicheng open pit,the response spectrum analysis was done of two holes blasting vibration with different microsecond delay time.Firstly,the acceleration signal was obtained by direct differentiation method using monitored of VOD signal,the accurate and clear accelerating curve was gained by LPF(low pass filtering) De-noising processing... |
