Abstract
Based on the numerical modeling results, the authors have revealed the features of stress state in the vicinity of development and stope workings in the course of the upward slice chamber-and-pillar mining under the open pit bottom in terms of the mine “Aikhal”. The optimal layout of access entries and their mining sequence in a layer are substantiated.
