Formulation of the Problem for Calculating the Stress State of a Pillar for a Longwall Recovery Room

Two statements of the problem of calculating the stress state of pillars for a longwall recovery room are proposed. In the first statement, this pillar is located in the coal seam and is not affected by the adjacent extracted panel. The second statement takes into account the geomechanical effect of...
