Abstract
Overview ? Case history of footwall slab failure ? Procedure used to build a finite element model ?? Pre- and post- mining topography ?? Slab geometry ?? Excavation stages ?? Input parameters ? Finite element modelling results ?? Unloading-induced displacements (magnitudes & directions) ?? Calibration of overall model using measured prism displacements ?? Shear stresses and displacements along the base of slab ?? Factors of safety at different stages ?? Effectiveness of rock bolts ?? Staged or unstaged model? ? Conclusion
