Abstract
The features are considered for shear and normal stress concentration at the interface of enclosing rocks with a seam during its mining. The relations determining the parameters of support pressure zone depending on the seam occurrence depth, its dip angle, length of the mined-out section, lateral pressure coefficient, and the average specific weight of the overlying rocks are presented. Conditions of origination and character of shear failure manifestation on the contact between the seam and the rocks beyond the peak of support pressure are defined.
