A procedure based on the nonlinear finite element analysis was investigated for the prediction of subsidence caused by longwall mining. This paper presents a case study involving predictions of subsidence at a coal mine panel for which a considerable amount of data was available in the literature. Some aspects of the selection of material properties and the shape of the subsidence profile are discussed.
