The Influence of Relative Distance between Ledges on the Stress-Strain State of the Rock at a Face

Abstract:

the effect of distance between ledges on the stresses in the rock of the face and distance between ledges as a function of the distance to the axis of a working are described, presence of a critical ratio of distance between ledges to the thickness of cut layer and the features characterizing the central area of the face are revealed.
