Trial measurements were aimed at investigating the peak particle velocity (PPV), which usually enables some criteria for the limitations of damage extent to be derived, e. g. of surface residential buildings, workings underground, failure and/or wall sliding. While rockbursts in hard-coal mines represent the source of recorded seismic waves, as opposed to that, shot-hole explosions for generating seismic waves in open-pit mines were used. Based on the regression analysis of the results of PPV experimental measurements vs. the square-root scaling factor for rockbursts and cube square factor for hole-shot explosion were applied, the slopes b of straight lines on the bilogarithmic scale were derived, i.e. b = -0.962 and b = -1.894, -1.843 and -2.256, respectively.
