Estimating shear strength of high-level pillars supported with cemented backfilling using the Hoek–Brown strength criterion

Deep metal mines are often mined using the high-level pillars with subsequent cementation backfilling (HLSCB) mining method. At the design stage, it is therefore important to have a reasonable method for determining the shear strength of the high-level pillars (i.e. cohesion and internal friction an...
