Objective is research of zonal structuring of massif around mine workings. The main methods of research conducting are following: equivalent, optic-polarization and electri-cally conductive materials. Boundaries of zones were determined according to magnitude of stresses γH. Results of research of zones parameters on physical models showed possi-bility of visualization of massif zonal stress, ellipsoid shape of zones and their centraliza-tion relatively to workings. Relations of vertical and horizontal semi-axes of zones for development workings and stoping chambers are established. Repeatability of received values is determined.
