Abstract
Under consideration is the stress-strain state in the edge area of a bed when mine faces approach a vertical fracture. The author illustrates the stress-strain state analysis using the previously derived analytical solution for a single pillar located symmetrically in a mined-out void. Comparison of the analytical and numerical results shows their admissible precision.
