Abstract: A method for determining the seismic safety distances for blasts in open-pit mines, taking into account the dominant frequency of the vibrations is discussed. The method is based on a regression analysis of the experimental data; the structure of method is characterized by a familiarity and easiness. The safety factor is used as the seismic hazard criteria. This factor is the ratio of peak particle velocity to its maximum allowed value adopted by the Regulations. Instead of peak particle velocity may be used other parameters of vibrations, such as the maximum displacement. It is also allowed the use of the mixed criteria of seismic hazard. The quality of regression is evaluated using the statistical analysis of residues. The proposed method is exemplified in seismic hazard analysis on one of the Kuzbass coal pit mines.
