Automated seismic monitoring in Vostochny Mine of Apatit’s Kola Branch: Hardware/software solutions

This study concentrates on creation of an automated seismic monitoring system at the industrial infrastructure of Vostochny Mine, Apatit’s Kola Branch–ASM VM–in the Khibiny Massive on the Kola Peninsula. The monitoring network embraces 11 seismic stations arranged around the mining area of two open pit mines: Koashva and Niorkpakhk. Seismic vibrations are recorded by velocimeters HS-1 connected to seismic recorders Ermak-5. The data are sent to an information accumulation and processing center in real time via cellular communication. The seismic stations are supplied by independent systems of wind power generators. For maximizing precision of seismic event coordinates in the test area, a 3D model is built including the natural landscape and the mined-out space. The physical properties of the medium are revised with the help of the earlier information on seismic profiling and rock petrophysics. For locating seismic events using this model, the dedicated algorithms are developed based on the representation of the medium as a stochastic graph. Over the period of 2020–2022, ASM VM disclosed natural seismicity zones within the monitoring field. When accumulated, the seismic monitoring data enable tracing seasonal variations in seismic activity. The research findings provide grounds for the risk reduction in open pit mining in Vostochny Mine of Apatit’s Kola Division.
