摘要：
The article presents the analysis of seismic observations in mine roadways. The recorded seismic signals are connected with dynamic deformation of rock mass under massive blasting. The source of induced seismicity are dynamic movements deformation of rocks with an amplitude of 3-30 mu m along fractures 1-15 m long. These events feature low values of reduced energy, probably, due to shallow depth of mining. Distribution of induced seismicity events in time and space agreed with patterns of larger seismic events due to remote earthquakes, which implies weak probability of nasty geodynamic phenomena in the course of mining in the Korobkov Field.
