Research of the formation of zones of stress concentration and dynamic manifestations based on seismoacoustic monitoring data in the fields of the Kola Peninsula

Abstract

The article presents the results of geomechanical studies to assess the rock-bump hazard of the rock mass in the deposits (Kukisvumchorrskoe and Apatite Circus) of the Kola Peninsula using a special set of technical means, including the automated seismoacoustic system for monitoring rock pressure, “Prognoz-ADS”, and the local geoacoustic device “Prognoz-L”, developed at The Institute of Mining of the FEB RAS. Based on the measurement and analysis of parameters of seismoacoustic events reflecting geomechanical processes in the developed mountain range, we constructed maps of seismoacoustic activity and volumetric mining and geological models of mines. Using these tools, it becomes possible to assess the rock-bump hazard in these deposits and identify hotspots for emerging dangerous geodynamic events at an early stage, which allows us to take the necessary security measures to prevent them in advance.
