ABSTRACT
The testing of the geomechanical system was begun with an analysis of the structure influence of the immediate and main roof of the coal seams. In the works, besides the main patterns of the rock pressure manifestations in in-seam workings of the Western Donbass mines, the so called “stamping effect” has been revealed, when the rock seam of an immediate roof with an increased rigidity and hardness “presses-out” the softer bottom rocks into mine working cavity due to formation of the increased rock pressure (IRP) zones in its sides. The technique has been developed of a computing experiment including seven consecutive stages of the stress-strain state (SSS) calculation of a system and its analysis for the most objective reflection of the system behavior in the range of changing its parameters, which are typical for mining-and-geological and mining-engineering conditions of the preparatory mine workings maintenance in the Western Donbas.
