Abstract
Several years of intensive research on modelling and prediction of ground subsidence in mining areas have led the authors to the development of a method, known as the S-C method, which is based on iterative linear elastic analysis combined with an empirical knowledge of the general behaviour of rock masses and their in situ mechanical properties above mine workings. The non-linear behaviour of the rock masses is modelled by a linear elastic finite element analysis in which zero values of Young's modulus are iteratively introduced in the directions of the critical tensional stresses in individual (anisotropic) elements.The concept of a so-called weak zone of rocks is introduced in order to reduce propagation of tensional stresses. The weak zone represents the distressed and tensiond rocks above the mine opening. It is delineated by the elements with maximum shearing stresses. The S-C method is supported by software FEMMA for two- and three- dimensional finite element analyses.
