Abstract/Summary A numerical model for flow using the Discrete Element Method (ESyS-Particle) was developed and validated against data reported in recent literature. An analysis of a range of flow models was conducted showing features of flow which are normally difficult to observe or measure in physical models or operating cave mines. Porosity and velocity data describe a movement zone which is very dense within the plug flow region and grows in waves of compaction and decompaction. The model was then extended to incorporate a wide size distribution of blocky particles able to interlock with each other. Results show a significant divergence from the ellipsoid of flow theory to one of a more turbulent and haphazard nature.
