Analysis of the current state of blasting operations has shown that further growth in the intensity and scale of blasting operations is constrained by the harmful effect of seismic waves caused by blasts on the environment. In order to avoid such action of seismic waves, as well as to increase the efficiency of blasting and to ensure seismic safety of blasting works it is necessary: to determine more accurately the parameters, intensity and permissible levels of the impact of seismic blasting and take into account the influence of various factors of seismic blasting.
