One of the methods of solving the problem based on a phenomenological approach that takes into account the nonlinear effects occurring in rocks under stress over ultimate stress limit is considered. The size of the inelastic deformation zone around a single mine working with different shape of cross-section are identified. The analysis of the influence of form of a single mine working with the specified height and width ratio on the size and shape of zones of inelastic deformation around a mine working is done. The comparison of the parameters of an area around a circular working and a working of another shape is fulfilled.
