The analysis of methods for determining the permissible speed of seismic vibrations of the soil at the base of the protected objects of Satka town. The maximum permissible values of the rate of vibration of the soil were determined for the buildings and structures of the industrial site of the Karagaiskiy quarry of the mining enterprise PJSC “Kombinat “Magnezit” (buildings of the administrative household plant, underground steel water pipeline, pump station), as well as for residential and industrial buildings. Approximating functions are constructed and empirical correlation equations are obtained for the mining and geological conditions of the Karagaiskiy quarry, confirming the equation of M.A. Sadovskiy. Actual seismicity coefficients and seismic wave attenuation indices were determined based on instrumental measurements of the speed of seismic vibrations of soil at positive and negative rock temperatures from 2004 to 2019 for the geological conditions of the Karagaiskiy open pit in order to refine and evaluate the seismic safety of residential and industrial buildings, structures and natural infrastructure facilities of Satka town, Chelyabinsk region. Design decisions on the seismic safety of guarded facilities during blasting operations in cramped conditions during mining of the north-western section of the Karagaiskiy quarry were confirmed and the parameters of drilling and blasting operations ensuring the seismic safety of guarded facilities were clarified.

The analysis of the values of the permissible speed of seismic vibrations and the calculation of the limiting values of short-term vibration at the base of the protected objects of Ust-Katav town and the settlement of Maliy Berdyash are carried out. Instrumental measurements of the speed of seismic vibrations of soil and pressure at the front of an air shock wave (air blast) during a large-scale blast in a quarry of building stone (dolomites) of «Ust-Katavskiy Granite Quarry» LLC (UKGK) were carried out in order to determine and evaluate safe seismic and shock air the impact of blasting on residential buildings in the settlement of Maliy Berdyash and the building of a special comprehensive boarding school in the Ust-Katavskiy urban district of the Chelyabinsk region. The conditions for blasting that provide seismic safety of protected objects are determined.
