Abstract/Summary This paper provides an overview of a new granular flow-deformation simulation technique based on a coupled Newtonian Cellular Automata (NCA) representation of the cave muckpile with an explicit Discontinuum Finite Element (DFE) model of the rock mass. The method emerged from the need to study the impact of draw and gravity flow on the initial propagation of the Ridgeway Deeps Block Cave, and the resulting interaction with the Ridgeway Sub-Level Cave (SLC). Data was transferred between the codes at a cave propagation time-step of 2 weeks, resulting in a high resolution representation of undercutting, draw and cave propagation; in total 32 coupling steps were implemented. All known structures were modelled including the 14 major faults and 29 intermediate scale mapped structures. The modelled cave backs were found to have good agreement with actual measurements.
