THE INCLUSION OF RHEOLOGICAL PROPERTIES OF ROCKS TO CALCULATION OF STRESS-STRAIN STATE OF AN UNDERMINED ROCK MASS

摘要

The procedure proposed for calculation of deformation and collapse of underworked strata is based on using the stiffness calculation matrix, representing the pre-mining state of rocks. The initial stress method is employed to account for variations in elastic constants in the deformation area in terms of the linear viscosity-elasticity. Potentialities of the described approach are considered. A number of solutions to the research problems are presented.
