A central system can drive mine trucks on fixed routes while people supervise and manage exceptions remotely.
Collections: Queue eliminated · Embodied work
Executive brief
The role redesign is fleet supervision and exception recovery, not simply replacing a driver with software.
AI value · Truck operating time and cost
Company-reportedIn 2018 each autonomous truck was estimated to operate 700 more hours on average with 15% lower costs.
Company estimate; mine mix and operating context affect transferability.
Before
Drives heavy haul truck along mine roads and intersections. → Coordinates vehicle assignments and traffic.
After
Navigates trucks on predefined GPS courses using fleet position, speed, and direction data. → Monitors fleet flow and intervenes for exceptions.
Human boundary
The system controls routine driving; central controllers authorize operations, manage traffic, and stop or recover vehicles.
Why it matters
A central system can drive mine trucks on fixed routes while people supervise and manage exceptions remotely.
This case is company-reported. Use it for the operating-model shift; do not treat the numbers as independently measured.
Before
How the work ran before the change.
Truck operator

ControlOperator judgment and mine traffic rules.
Dispatcher

ControlSite operations control.
What changed
A central system can drive mine trucks on fixed routes while people supervise and manage exceptions remotely.
Decision rightAI handles the default; humans own exceptions
After
How the same work runs now.
Autonomous haulage system
Navigates trucks on predefined GPS courses using fleet position, speed, and direction data.
ControlSupervisory system and central controller.
Central controller
Monitors fleet flow and intervenes for exceptions.
ControlHuman operational authority and exclusion zones.
Exception path
Faults, obstacles, or route anomalies stop the vehicle and escalate to central control and field teams.
Decision authority
The system controls routine driving; central controllers authorize operations, manage traffic, and stop or recover vehicles.

Work that left the path
Human role before
Operators drove each truck in a hazardous heavy-equipment environment.
Human role after
Controllers supervise fleets and field teams manage maintenance and exceptions away from routine driving exposure.
AI role
Decision mode: bounded autonomous navigation on mine roads.
Conventional human-driven haul trucks.In 2018 each autonomous truck was estimated to operate 700 more hours on average with 15% lower costs.
2018 operating estimate. · More than 130 autonomous trucks across Rio Tinto iron-ore operations at source observation.
Company estimate; mine mix and operating context affect transferability.
Drivers worked around heavy machinery for routine haulage.Routine truck operators were removed from the autonomous driving task.
More than a decade of operation. · Pilbara iron-ore fleet.
Overall injury rates are not attributed solely to haulage automation.
Anti-pattern
Inferring whole-site safety improvement from removal of one exposure pathway.
