Integrated Haulage Strategy

Integrated haulage strategy cuts costs

Maptek recently added the Evorelution capability to Vulcan, providing advanced strategic mine scheduling optimisation tools.

Now known as Maptek Evolution, Evorelution proved its worth in a scheduling study at the Tropicana gold mine in Western Australia in 2012.

One large block model covered the Tropicana project, which extended more than 5km along strike and to a depth of 400m. Ten waste destinations were involved. Practical medium and long-term mine plans were developed from the resource model.

The mine plans met mill feed requirements while minimising haulage costs, maximising recovered metal production and minimising stockpile rehandle.

The efficient scheduling process reduced the time to generate optimal fleet haulage routes for the 10 waste landforms.

Analysis revealed that purchasing three extra trucks could be delayed for 18 months, saving more than 1,000 haulage hours per month for this period.
