This paper presents a simplified method, based on the displacement discontinuity method, to conduct stress analysis for tabular mining. In this method, the average displacement discontinuities of each excavated panel are first estimated by considering only mining conditions. Then, displacements and stresses at any point including the ground surface are calculated by substituting the average displacement discontinuities into the solution of an elastic problem for a point dislocation in a
