Material flow analysis is required where rock is moved from its initial position to an extraction point by gravity, such as in mining by sublevel, panel or block caving. Appropriate gravity flow modelling can help reduce ore contamination from adjacent or overlying waste. Stochastic methods provide a powerful tool for modelling gravity flow, allowing for optimisation of extraction, reduction in dilution and maximisation of mine revenue.
