Shu, A. Bhattacharyya] Summary: This paper deals with the determination of subsidence parameters on a sloping ground surface above a completely mined underground panel in an inclined seam. A rays projection method is analytically developed to derive the subsidence components on the sloping ground surface from the corresponding ones on an assumed equivalent horizontal surface through the point of the mean elevation of the sloping surface above the extracted panel. Using the derived equations, the variation of subsidence with the inclination of the ground surface is analysed. An example is given to illustrate the application of the rays projection method in predicting subsidence effects on a sloping surface.
