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.
