Calculate haulage while scheduling Maptek

Many open pit operations are in reality waste mines due to high stripping ratios. The cost of waste mining effectively drives costs. Optimising the waste as part of the scheduling process inherently leads to an optimal schedule and therefore maximises value. Accurate waste location data is vital for obtaining accurate haulage hours for scheduling.
