This thesis presents a digital computer numerical method for predicting subsidence over flat-lying seam-type deposits. The method is based on a two-dimensional transversely isotropic, elastic solution given by means of the displacement discontinuity method. This numerical method is versatile and can be applied to irregular extraction patterns in single and multiple seam mining situations. The elastic constants necessary to describe the rock mass behavior were obtained by using a back calculation procedure and measured subsidence data. Predicted subsidence profile was found in close agreement with a measured subsidence profile. In the multiple seam situations it was found that presence of previously mined seams above mined panels produces a marked increase in subsidence.
