DEFORMATION AND FAILURE OF ROCKS AROUND UNSUPPORTED MINE WORKINGS UNDER CREEP CONDITIONS
The model based on the maximum shear stress and the power law, was employed to solve the problem on deformation and failure of a cylinder-shaped mine working under creep conditions. Stress, strain, yield, location and rate of the failure front advance are evaluated at any study moment. New solutions for a plane deformation of an elastic-creeping rock mass under unstationary creep conditions are obtained.
