Abstract
Consideration is given to the causes complicating the mining of shaftbottom pillar and protection of shaft lining. The analysis is given to the formation of stress-strain state of the protective pillar and its enclosing rocks. Practical recommendations are given for control of deformation and stresses in the shaftbottom mass during extraction of protective pillars in deep ore mines at Talnakh.
