摘要(Abstract)：

为深入了解新疆别斯库都克露天煤矿爆破振动信号的特性,应用小波变换方法对监测所得的非平稳爆破振动信号进行了时频特征分析,获得了爆破振动信号小波多分辨率分析的各频带能量分布规律,给出了振动信号的细节特征,为爆破设计人员更好地指导爆破设计,进一步改善爆破效果及降低爆破振动效应提供一定参考。
In order to study characteristics of blasting vibration signals of the Biesikuduke open coalmine,time-frequency characteristics of the non-stationary blasting vibration signal have been analyzed based on wavelet transform.Laws of energy distribution of each frequency band by using wavelet multiresolution analysis and the minutiae of vibration signals were obtained.It could help to guide the blasting design,improve blasting effect,and reduce the blasting vibration effect.
