Abstract: The article presents a summary of perennial research results regarding the issue of hazardous zone formation during mining operations in the Khibiny natural and technological system. The fundamental mechanisms of rock mass failure and regularities of formation of three types of hazardous zones in vicinity of mining technology elements have been determined with consideration of the man-made stress field parameters, structural heterogeneities and rock properties. Zones of high occurrence probability of the most hazardous geodynamic phenomena are identified which develop as a result of fault activation and movements of structural blocks along these faults; zones where dynamic events occur in immediate proximity from the excavation front or inside the pillars in conditions of compressive stresses concentration, which level approaches or exceeds the limit of the rocks compressive strength; zones where seismic events occur in the undermined rocks accompanying formation and development of ruptures in the hang-ups. Options are proposed for prediction and localization of each type of high geodynamic activity zones.

Keywords: rockburst hazard, rockburst, man-made earthquake, induced seismicity, monitoring, Khibiny rock mass, stress-andstrain state, failure mechanisms, mining operations
