PGCA
PGCA (Power Geotechnical Cellular Automata) is a particle to particle-based flow modelling technique, which can account for material properties, cave back constraints and other properties which are influential in the flow of broken rock.
It has been shown to readily calibrate on an operational level, making it an accurate forecasting and planning tool.
The speed and flexibility of PGCA allow rapid assessment of all types and sizes of caving operations, and contains shutoff algorithms that can be used to optimize resource recovery.
The approximate run time for a 70Mt sub-level caving case (containing 20,000+ production rings) is approximately 2 hours using a standard desktop computer. Block and panel caving cases generally run more rapidly. An example of a 160Mt panel caving case takes approximately 10 minutes to run.
