Haulage

This topic introduces the fundamental concepts of haulage simulation. Truck haulage and haulage-related costs can account for a considerable proportion of the total operating costs incurred by a mine. As such, under-performance or poor planning can impact strongly on the mine’s productivity and the bottom line. Haulage simulation plays an important role in identifying opportunities for improvements, testing the viability of haulage plans and managing considerable financial assets.

Running haulage simulation and analysis requires both a multi-step setup and the use of haulage logic controls. Haulage Setup includes providing an input schedule, relevant equipment/truck specifications, road specifications (speed restrictions and segment codes), and the creation of haulage networks.

Truck/Fleet Performance

Once your haul environment has been determined, the next stage is to choose which truck fleet options you wish to simulate. The following links summarise the parameters of truck performance used in the application:

• Rolling Resistance

• Effective Grade (Static Force)

• Rimpull

• TKPH

• Coefficient of Traction

  Note: Coefficient of Traction rarely enters into the frame, but is included for completeness.
