【 摘 要 】

Under analysis is the stress state of rock mass surrounding stopes in the initial cutting layer displaced in plan relative to the above-lying extracted layer in the overcut rock mass. The authors determine the boundaries of the post-limiting deformation zones during stoping advance using the Mohr-Coulomb criterion. The sequence of stoping to ensure better support conditions is proposed.
