| 摘 要： | Based on the measuring data of underwater blasting vibration and the regression analysis results of these data, two formulae usually used of blasting vibration velocity were compared. Factors that can affect blasting vibration and frequency were summarized and analyzed. It is thought that the effect of the number of freedom face and burden direction on blasting vibration should be considered during blasting design. Based on the relevant research results and the regression results of these data, a formula to calculate under water blasting frequency was put forward.
