Development of Parameters for Numerical Modeling of Geomechanical Systems "Excavation - rock mass - support"

The airway drift of “Trudovskaya” mine of “DTEK” company was chosen as an object of research because of strong effect of rock pressure and water influence in the excavation. The main forms of rock pressure in the excavation are rock falling from the side and the roof, and intense swelling. The main purpose of numerical simulation is to justify the parameters of the support systems of the excavations, which are exploited in the “Trudovskaya” mine. As a test model was accepted a model which reflects a real situation in the vicinity of excavation

NUMERICAL SIMULATION OF JOINTED ROCK MASS IN GEOMECHANICAL PROBLEMS

Study the possibility of realistically numerical simulation of a jointed rock mass and estimate the design rock mass strength involving discontinuity surface conditions and various shapes and sizes of rock blocks
