Assessment of geomechanical behavior of rock mass by the data of seismic monitoring with acoustic sensing at rockburst-hazardous deposits

This study analyzes rockburst hazard in underground mines on the Kola Peninsula and in the Far East of Russia. In these areas, the whole spectrum of dynamic events caused by rock pressure and the induced seismicity are recorded. The research was implemented using dedicated instrumentation for ground control, including acoustic sensing and seismic monitoring system Prognoz-ADS and local geoacoustic sensing device Prognoz L, both designed at the Institute of Mining of the Far East Branch, Russian Academy of Sciences. After recording and analysis of geomechanical processes in rock mass, the zones of stress concentration were delineated, the acoustic and seismic activity maps were plotted, and the geological model of the test mine was constructed on this base. The instrumental measurement data enable rockburst hazard assessment and early detection of initiation sources of hazardous geodynamic events at mineral deposits, which ensures prompt implementation of the required prevention and precaution.

Keywords: rock bursts, prediction, induced seismicity, geodynamic safety, geological model, acoustic sensing and seismic monitoring, geomechanical processes.
