... on areas of known concern, are analysed. Kinematically admissible joint orientations are incorporated as ubiquitous joint models and materials are modelled based on the Mohr-Coulomb failure criterion. Limit equilibrium method results revealed that profile A is the most critical slope, with a significant...

..., interruption of production, and in the long term, even reduction in the life of mine. Rock engineering designs therefore need to take such consequences into account, to the extent that ‘value’ should perhaps be a design criterion. In this keynote paper, I shall be summarizing outcomes of rock engineering...

... and outside the plastic zone. A Maple program was written to derive the expressions of plastic zone radius and stresses when adopting either the Mohr-Coulomb criterion or the Hoek- Brown criterion. The two approaches were then compared. All analyses were conducted on two hard rock types: granite and limestone...

... FLAC3D was employed to assess pillar and panel stability for a partial stooping operation at a coal mine in South Africa, where the main requirement was that ground surface stability be ensured. The stability of square and rectangular pillars was assessed using a strain criterion linked...
