Abstract
Experimental research determined the concentration zones of seismic events and their sources in operating Taimyr Mine. The features of formation and spreading of these zones are assessed. The influence of mined-out void volume on total energy of seismic events before and after flooding and dewatering of mines is analyzed, which allows predicting the level of seismic hazard during further mining.
