Numerical Modelling for Prediction of Ground Subsidence Over
WEBJan 1, 2023 · The main objective of this study is to predict the surface subsidence due to the extraction of coal seam from an underground mine. The mining method is room and pillar and complete pillar recovery through depillaring and simultaneous stowing with sand. The coal seam roof level is loed at a depth of 121 m below ground level.
