| Abstract: | We solve the problem of the normal and transverse shear in an anisotropic monolith during the excavation of a stratum of solid
mineral. It is shown that the stress perturbation field in the rock is due to the whole extent of the excavated portion of
the stratum. We study way in which the friction that arises between the interacting rock of the roof and the floor influences
the strain and stress fields as the front of the excavation evolves, and also the influence of the extent of the excavated
portion of the rock stratum on the magnitude of the accumulated tangential displacements. Three figures.
