A numerical procedure for the computation of the displacements and stresses induced by the mining of a tabular ore deposit in faulted ground is described. The procedure is based on the displacement discontinuity method, which can be regarded as an application of Salanon's 'face element principle' to cases in which the reef plane is faulted into several sections, or even folded in an arbitrary way. An element of a fault is modeled in the same manner as an element of the reef, except that a fault element is allowed to undergo permanent inelastic deformation (i. e. , slip) if the stresses transmitted through the fault-filling material satisfy a Mohr-Coulomb yield condition. An iterative technique for the incorporation of a Mohr-Coulomb yield condiion in the general displacement discontinuity method is explained. This technique is illustrated by means of a simple example involving the mining of a flat-lying reef intersected by a fault.
