Autonomous Haulage - Business Case

Results indicate that cut-offs for the application are presently in excess of 12 Mtpa of total earthmoving. All of the current implementations of an AHS are based in mines that exceed this amount of total material moved.
Truck count cut-off thresholds vary by payload capacity, but a minimum of six to eight trucks is generally required. In its present form, an AHS is therefore not likely to be applicable to all surface mines as scale is a key factor.

The mining boom and political risk

VANCOUVER: After a nine-year lull, investors are fast-taking notice of the once-neglected precious-metals sector.

Australia has some of the largest open pit quarries and underground mines in the world. However, due to lack of proper planning, a majority of these mining sites have been abandoned. 

 

In recent years, the government is using modern day drone and laser scanning technologies to reimagine these mining sites. With UAVs, engineers can easily collect on site data, explore underground quarries and also ensure…

An indisputable potential advantage of autonomous vehicles is that they could provide increased safety, both on the road and near mining sites. Vehicle software is likely to make fewer errors in comparison to humans, meaning automation could decrease the number of casualties in mining operations.

After Fortescue completed its leading autonomous haulage project in October 2020, one of the largest fleet conversions to autonomous haulage in the industry, the company is ramping up its…
