The issues of the causes and factors of manifestation of seismic activity during the extraction of minerals in the deposits of the Khibiny massif, which are mined underground, are considered. Based on seismic monitoring data, groups of seismic activity were identified, such as seismicity in the working area, directly related to blasting and natural seismicity, related to other mining and geological factors. The difference in the characteristics of the manifestation of seismicity for these two groups of seismic events is shown.

The effect of water saturation of the medium on the ability of earthquakes to initiate repeated shocks (productivity) is considered based on the long-term seismological observations and water inflow monitoring data from the Khibiny massif ore deposits. The study indicates that the water saturation of the medium is a factor that has a significant impact on the productivity of earthquakes.
