Abstract

The experience gained in simulation of geomechanical processes in longwalls and development drifts in underground mining of solid minerals using models of equivalent materials is analyzed. The relevance and practical significance of solving problems connected with the study of dynamic geomechanical processes in rock masses of block and layered structure, characterized by deformation and discontinuities are emphasized. The study of such issues in the production environment by analytical methods is very difficult and, in some cases, impossible. The general methodology is proposed for modeling processes in rock masses of block and layered structure based on the developed set of similarity criteria, types of equivalent materials and technical solutions that provide both measurement of static and dynamic stresses and parameters of other physical fields in models of equivalent materials. Application of this methodology to study regular patterns of change in the dynamic parameters of geomechanical processes in block and layered rock masses under mining-induced transformation of their structural parameters is exemplified.
