Abstract: Vibration, the most widespread environmental harmful effect during engineering blasting, is often given special attention and strictly controlled. In order to explore the difference between seismic waves excited by carbon dioxide phase transition blasting and explosive blasting, a comparative study was carried out through on-site vibration monitoring and signal analysis. The results show that under the same explosion energy condition, the peak particle velocity of ground vibration caused by a dry ice fracturing cylinder is far lower than that of an emulsified explosive; Although the former's vibration duration is slightly longer, the primary frequency of FFT is higher, and the proportion of low-frequency energy is small, which is not easy to cause resonance of buildings (structures). When carrying out engineering rock-breaking operations in complex and sensitive environments, carbon dioxide phase change blasting technology can be prioritized.
