Cluster location procedure for technogeneous seismic events in deep mines

The review of the current underground seismic monitoring and location methods of seismic events is followed with presentation of a new, cluster location procedure for mining-generated (technogeneous) seismic events, including isolation of areas where waves run to sensor at approximately equal velocities, cyclic calibrating blasting and then cluster location of seismic events, occurred within the isolated areas, by iterative procedure. The offered method is illustrated in terms of an ore massif in the Oktyabrsky Mine, Norilsk ore deposit. The method showed up to be able to appreciably adjust vertical coordinates of seismic events and to determine the associated tectonic structures.
