ABSTRACT
This paper presents the stability assessment of a filtered, dry-stacked, iron ore tailings storage facility using 3D limit equilibrium methods. Slope stability assessments were performed using Rocscience’s Slide3 software. For comparison, 2D stability analysis of a cross-section derived from the Slide3 model was also completed using Rocscience’s Slide2 2D limit equilibrium software. Both analyses demonstrate the ease and speed at which Slide3 and Slide2 can model and analyze even the most complex 3D geologic structures. The results show the importance of 3D and 2D stability analysis where undulating topography forms the foundation of tailings storage facilities.
