ABSTRACT
In the current conditions of the intensive Mineral Deposit (MD) mining and the growing complexity of the mining and geological setting, geomechanical processes, while continually developing in space and in time in structurally damaged rocks under the effect of various natural and man-caused factors, are taking expressly non-linear forms appeared as a change over time in different structural parameters of rock mass, and its Stress-Strain Behaviour (SSB) both in quasi-static and dynamic modes. The modelling method based on Equivalent Materials (EM) is one of the most effective study methods for deformations and damage in large rock masses at the MD mining which allows the most adequate simulation and study of their physical behaviour. The new simulation methodology developed on its basis and the study of different structures, physical fields and their evolution enabled to study the physical principles of the reviewed geomechanical processes more deeply, to enhance the reliability of a prediction on their basis and the prevention of dangerous dynamic phenomena. The developed innovative modelling technology allowed us to solve a number of perspective fundamental and application problems in the mining geomechanics through the obtainment of the new data on the physical processes happening in space and in time.
