A study was conducted to compare physical and numerical models of the block-caving mining method. Results from the numerical analysis closely simulated the blocky behavior of the physical model, including bridging and interlocking of the simulated orebody during draw. The draw-down patterns and the rate of draw developed during numerical modeling also closely simulated the physical models. An unexpected result from the numerical modeling was the development of a zone of downward deflection which preceded the development of the zone of material movement.
