摘要(Abstract)：

为分析二氧化碳相变爆破产生的振动信号特性在时间上和空间上的衰减规律，通过现场二氧化碳相变爆破试验，分别对距离爆源处5、8、12 m位置设置质点速度监测仪，分别对得到的爆破振动信号进行频谱、能量谱分析，得到关于二氧化碳相变爆破振动信号在空间和时间上的衰减规律。随着距离的增加，低频部分逐渐衰减只剩下高频段部分。在能量的分布上，二氧化碳相变爆破的能量主要分布在中低频段(0 HzIn order to analyze the temporal and spatial decay patterns of the vibration signal characteristics generated by CO_2 phase change blasting, by carrying out the field carbon dioxide phase change blasting test, a partial velocity monitor was set at positions 5, 8 and 12 m away from the detonation source respectively to conduct spectrum and energy spectrum analysis of the obtained blasting vibration signal, and the attenuation law of carbon dioxide phase change blasting vibration signal in space and time was obtained. As the distance increases, the low-frequency part gradually decays and only the high-frequency part is left. In terms of energy distribution, the energy of carbon dioxide phase change blasting is mainly distributed in the middle and low frequency band(10 Hz
