Abstract
The requirements for achieving numerical geomechanical estimates close to real conditions are substantiated. Limitations in modeling which predetermine the reliability and accuracy of prediction of the rock mass mechanical behavior and mining structures are identified. It is shown that creation of a geomechanical model for an existing or newly developed mine allows to solve the problems of the operational choice of the method of rock mass state control at the opening, preparation and stoping stages at a qualitatively new level. This will also help to develop a set of scientifically justified recommendations and engineering activities for safe deposit mining at different phases of mining operations with acceptable risks for the enterprise. When performing numerical modeling, special attention should be paid to rock mass fracturing
