Abstract: Forecasting of the geomechanical situation when planning mining operations at rockburst hazardous deposits is an essential component in ensuring safety and developing measures to reduce geodynamic risks. The paper presents the results of assessing and forecasting the transformation of the stress-and-strain state of the rock mass for one of the promising mining sites of the Khibiny Apatite Arc. All calculations were made using elastic approach to a three-dimensional finite-element model which incorporates basic geological, mining engineering and geomechanical data. Potentially hazardous zones in terms of dynamic rockburst manifestations were identified as well as areas with different deformation and collapse patterns in the undermined rock strata. The identified features of the stress-and-strain state of the rock mass make it possible to increase the justification level of technical solutions for the development of mining operations and designing preventive measures to ensure the stability of the mining system's elements.

Keywords: tectonically stressed rock masses, stress-and-strain state, underground operations, mining of near-edge and pit reserves, numerical modelling, rockburst hazard
