Abstract

It is known that rock in the sides of horizontal workings is destroyed either by shear along one or another sliding surface or by detachment of the near-contour zones of the rock mass along vertical surfaces. Failure by shear is well explained from the standpoint of the theory of limit equilibrium of a cohesionless medium. The second possible type of failure — detachment of near-contour zones — has so far no clear explanation.
