The article is devoted to the comprehensive study of the methods available for the stress–strain analysis of rock masses in terms of the Streltsovo ore field developed by Priargunsky Industrial Mining and Chemical Union (PIMCU). The experience of geomechanical monitoring of the Antey deposit is described. The methods of prediction and prevention of rock bursts in the areas of high stress concentration in host rocks are considered. The regional rockburst hazard prediction using ground control systems is described: automated rock pressure control (ASKGD) and automated wide-range rock pressure control (ASHSKGD). The scope of the review embraces the methods of obtaining space–time characteristics of the rock deformation process by the automated deformation data collection system (DMD); recording of microstrains in the earth’s crust in the infrasonic frequency range by a laser strain gauge; methodology for observing the displacements in mine workings with a Faro Focus 3D laser scanner. The scheme of accumulation of databases on the geomechanical conditions of the Antey deposit is described. The process of collecting information which allows real-time processing of seismic-acoustic data on rock mass as well as the methods for visualizing data on geomechanical situation in the form of maps of seismic-acoustic activity foci and rockburst hazard coefficients are presented. Sigma GT and ARGIS-10 software packages made it possible to create 3D mathematical model of the Streltsovo ore field for assessing the stress–strain behavior of rock mass using the finite element method.
