摘要：

The article presents the results of monitoring the seismic impact of bulk blasts during explosive breaking of iron ore in the Gubkin mine on the city of Gubkin. The dependence of the maximum oscillation velocity in a seismic explosion wave on the reduced (based on the mass of the explosive in the delay stage) hypocentral distance to the explosive chamber is obtained. For one bulk blast, an isoseist map was constructed, demonstrating the intensity of seismic impact on residential areas of the city. Taking into account the requirements of regulatory documents and duration of seismic and explosion vibrations, estimates of the permissible and maximum permissible velocities of seismic vibrations for the population have been obtained.
