REBOP is a code for rapid simulation of the flow of fragmented rock in cave mining operations. Along with a drawpoint layout and schedule, REBOP accepts a mine block model with expected caved-rock properties as direct input for easy set-up and running of mine-specific draw simulations. REBOP is capable of tracking the movement of material within caves that incorporate hundreds of drawpoints over production spans of several years. The code provides reports of drawpoint grades with time/tonnage and has been employed at several cave-mining operations to predict waste entry and recovery as functions of drawpoint layout and to guide draw control strategy.
REBOP was developed as part of an industry-sponsored study of caving mechanics, and its use is currently restricted to sponsors and Itasca. If you would like more information about REBOP and its capabilities, please contact
Matthew Pierce at Itasca.
 
REBOP models of block caving (left) and sublevel caving (right) are used to predict cave drawdown and ore recovery. The essential flow mechanisms observed in simulations conducted with PFC3D were incorporated into REBOP to permit rapid simulation of draw from hundreds of drawpoints over many years.
