Laboratory research of zonal structuring of massif around mine workings
MetadataShow full item record
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.
