On Possible Causes of Increase in Seismic Activity of Mine Fields in the Oktyabrsky and Taimyrsky Mines of the Norilsk Deposit in 2003. Part II: Oktyabrsky Mine

摘要

The data are presented for seismic events with an energy higher than 10~3 J that have taken place in the Oktyabrsky Mine from 2002 to 2003, and apparent velocities are estimated for regularly formed clusters of such events. A complex analysis is performed for the experimental measurements conducted for estimating development of deformation processes in rock masses during long-term mining of copper-nickel ores in the Oktyabrsky Mine field. Interconnection of the deformation processes and the local seismic regime is considered in the analysis.
