In order to explore the difference of vibration characteristics between high-pressure gas cracking and explosive blasting.The equivalent relationship between different gas pressure and explosive was established according to the blasting energy method of compressed gas and water vapor vessel,and the vibration test of high pressure gas blasting and explosive blasting in rock mass was designed and carried out.Based on the test results,the duration and vibration velocity of the 2 types of blast vibration were analyzed,and the wavelet packet transform technique was used to compare the distribution pattern of the energy of the 2 vibration signals in the frequency domain.The results show that the vibration duration of high-pressure gas cracking is much longer than that of explosive blasting,and the duration of both blasting vibrations decreases with the increase of distance.High-pressure gas blasting vibration duration decreases with the increase in burst pressure,but the duration of explosive blasting vibration increases with the large increase in mass.The peak vibration velocity of high-pressure gas cracking is smaller than the explosives blasting,but with the increase of distance,the peak value of 2 kinds of blasting vibration tends to be close,and high-pressure gas cracking vibration velocity than explosive blasting decay slowly.The main frequency bands of the two blast vibration signals shift to lower frequencies as the distance increases,and the proportion of energy in the main frequency band gradually decreases.Compared to explosive blasting,high-pressure gas cracking vibration signals are much lower and narrower in frequency,more concentrated in the frequency domain,and have a higher percentage of energy in the main frequency band.
