- A method for determining seismic safe distances for blasting operations in mines, taking into account the value of dominant frequencies of the earth surface vibrations is proposed. The method is based on a regression analysis of the experimental data; the method is characterized by a familiar and simple structure. The safety factor used as a criterion for seismic hazard is the ratio of peak particle velocity to its maximum allowable value adopted by the regulations, taking into account the dominant frequency. Instead of peak particle velocity, other parameters of vibrations may be also used, for example, the maximum ground displacement. It is also allowed to use mixed criteria of seismic hazard. The regression quality is evaluated using the statistical analysis of residuals. The method is based on the analysis of experimental data and therefore takes full account of both the particular way of performing blasting operations at a particular mining company, and the geological and hydrological conditions in the path of seismic wave propagation.
