The complication of mining and geological conditions is associated with the involvement in the development of areas and entire deposits with complex tectonics, an increase in the depth of development, the manifestation of dangerous dynamic effects of rock pressure, which necessitates the improvement of methods, systems, methods and means of supporting mine workings, as well as improving the quality of materials used for support. Mining and geological factors affecting the use of mining support include: the depth of occurrence, which determines the magnitude of the vertical and horizontal components of the rock pressure; layer thickness, developed deposit; bed angle; properties of the host rocks, structure and physical and mechanical properties of rocks and minerals. The paper presents the conduction of the analytical modelling of the rock mass stress-strain state around the active mine workings using the ANSYS software with the assessment of the influence of its cross-section shape and the angle of the coal seam fall on the value of the maximum stresses arising in the rock mass when the workings are supported with the anchoring support depending on the thickness of the easily collapsible rock layer at different lengths of anchoring.
