Abstract: The article considers a generalized approach to application of digital models of deposits and organization of geomechanical monitoring systems in the mining of ore deposits in Siberia based on experience of research work carried out by the staff of the Mining Institute named after N.A. Chinakal, Siberian Branch, Russian Academy of Sciences, in the interests of industrial partners. A scheme of managing geomechanical monitoring is given, which provides verification and adaptation of the geomechanical model to the changing conditions of the mined deposit. The results of determining the stress-and-strain state of the rock mass at the Aikhal mine and assessing the state of the ore ceiling are presented. With the use of numerical geomechanical models, a geomechanical justification is made for application of the technology with backfilling of the minedout space. The impossibility of using the mining systems based on caving is demonstrated when extracting the pit reserves of polymetallic mineral deposit. The conclusion provides proposals for organizing geomechanical monitoring with the use of digital geomechanical models.

Keywords: digital model of the deposit, geomechanical monitoring, stress-and-strain state, geomechanical model, stability assessment, numerical modeling

Acknowledgments: The work has been prepared with the support of ALROSA.
