Geotechnical Model Development For Caving Design

SRK performed a comprehensive redevelopment of the geotechnical model for an existing large panel caving operation with the aim of assisting cave planning and design in five future cave blocks. Initially, separate models were created for the individual blocks to allow for smaller, more focused models; however, a large all-encompassing model was subsequently created. The

Accounting For Micro-Defects In Rock Mass Rating

In 2001, Laubscher’s Mining Rock Mass Rating (MRMR) classification system (Laubscher and Jakubec, 2001) introduced the rock block strength concept to account for scale effects and the influence of closed defects on intact rock strength (IRS). Almost two decades later, rock mechanics practitioners are still challenged by how to appropriately incorporate defects, other than open
