“…A distinctive feature of dynamic manifestations of rock pressure, especially rock and rock-tectonic impacts, is their suddenness and great destructive force, manifested in the form of the release of ore (rock) into the mine with severe consequences: violation of the support, displacement of machines, mechanisms, equipment, causing a violation of the technological process. Rock impacts create a serious threat and danger to the life of workers, disrupts the normal course of mining operations and thereby reduces the efficiency of mining production [1][2][3][4][5][6][7][8].…”

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.

The results of geomechanical studies to assess the rock burst hazard at the deposits (Kukisvumchorr and Apatite Circus) of the Kola Peninsula are presented in the article. These results are obtained by special set of technical means, including an automated seismic acoustic rock pressure monitoring system “Prognoz-ADS” and a portable geoacoustic device “Prognoz L” developed at the Mining Institute of the Far Eastern Branch of the Russian Academy of Sciences. Based on the measurement and analysis of the parameters of seismoacoustic events, reflecting the geomechanical processes in the mined rock mass, maps of seismoacoustic activity combined with 3D mining and geological models of mines were developed. Based on the analysis of the spectral parameters of the signals, it was concluded that the use of the developed software and hardware complex is promising for predicting dynamic phenomena in the rock massif. The rock burst hazard can be assessed by the measuring complexes at these deposits; necessary safety measures can be taken for decrease of geodynamic risk.
