Abstract |
Having stated the highest priority of the increased accuracy location and forecasting of seismic events in rockburst-hazardous underground mining at Talnakh, the authors give a review of the existing approaches to handing the indicated problem, the implemented research and the algorithm developed based on the seismic monitoring results for location (coordinates) of seismic events and determination of their velocities, positions of hypocenters and initiation time of spaceand time-close seismic events. The research involved various mine-technical situations and geological structures governing the hazard range of a seismic event, and the prime measures aimed at increase in accuracy of location of seismic events, including the measures under implementation in operating mines of Norilsk Nickel. The authors describe some of the high-performance modern seismic stations and the applicable algorithms (computational methods) of location of seismic events, in particular, SPAM algorithm in seismic monitoring service in Oktyabrsky and Taimyrsky Mines. The authors’ algorithm has been trialed in Oktyabrsky Mine, under calibration blasting in the stoping zone, and the group location of seismic events is recommended as the best possible positioning of seismic events relative to mine workings and faulting.
