Special features of the Earth's crust structure in the area of the Krivoy Rog suture zone situated on the border of two megablocks of the Ukrainian Shield have been analyzed. The data obtained as a result of the Krivoi Rog super-deep well SD-8 drilling and conducting geophysical works by seismic methods have been used. The results of comparison of records and spectrograms of local earthquakes and industrial explosions in mines and quarries have been given. Origin of local seismicity with magnitude mb ? 3,0 has been considered, which manifested in zones of tectonic faults of the Earth's crust in the area of the Krivoi Rog structure in 2007-2011 in connection with technogenic loadings caused by mining of mineral wealth with application of powerful industrial explosions.
