| Abstract: | Summary Subsidence planning and control must be an integral part of mine design in order to minimize the economic impact of underground mining on the surface. Precalculation of surface deformations which may cause damage to surface structures must be performed and damage criteria must be established, if the response of structures to such movements is to be determined and the extent of damages to be assessed. In this paper the Surface Deformation Prediction System (SDPS), which can be used to predict accurately the vertical and horizontal parameters of surface movements due to underground mining, is discussed. The Subsidence Response Modelling Program (SRMP), which can be applied to evaluate the response of buildings to subsidence-induced movements, is also reviewed. Finally, an example is presented demonstrating the applicability of these techniques for subsidence design and control. |
