| Abstract: | A model of the geomechanical state for a rock massif with strength anisotropy has been developed. Themassif encloses an in-seamworking near the geological discontinuity. The developed models implemented on the basis of pseudo-load method and displacement discontinuity method. Based on the results obtained, stress diagrams and discontinuity zones of the massif in the vicinity of the mine working are constructed. The regularities of changing the state of the massif when its parameters are varied and the relative positions of the mine working and geological discontinuity are revealed. |
