ABSTRACT
A verbal scale of geodynamic risks has been proposed. Magnitudes of geodynamic risks for the Khibiny apatite mines have been estimated. Based on values of probable occurrence of geodynamic events a level of consequences has been determined according to the database with geodynamic events which had been officially registered in JSC Apatit mines by rockburst commissions for 1981 - 2015. It has been shown that the largest damage by geodynamic events is inflicted on mining excavations, i.e. on a technological process. That is why, besides forecast and assessment of geodynamic risks, the tasks of risks management are of primary importance.

Keywords: geodynamic risks, high-stressed rock mass, verbal scale
