That a person must drive each haul truck through repetitive mine cycles.
Collections: Queue eliminated
Executive brief
The transferable pattern is not driver elimination; it is relocating people from continuous exposure to fleet supervision, recovery, and maintenance in a controlled domain.
AI value · Truck-related significant events and haulage cost
Company-reportedMore than 90% reduction in significant truck events and 20% lower haulage cost versus other WAIO sites
Operator-reported before/after and cross-site comparison; cost differences may include mine-specific factors beyond autonomy.
Before
Drive repeated loading, haul, dump, and return cycles in the open pit. → Coordinate traffic and respond to vehicle events.
After
Controls repeated haul-truck movement within the mine operating area. → Supervise fleet flow, manage exceptions, maintain vehicles, and control access.
Human boundary
The system controls routine driving; remote operations and mine-safety personnel retain fleet, access, and emergency authority.
Why it matters
That a person must drive each haul truck through repetitive mine cycles.
This case is company-reported. Use it for the operating-model shift; do not treat the numbers as independently measured.

Exception path
Vehicles stop or are isolated when routes, obstacles, equipment state, or safety controls require human response.
Decision authority
The system controls routine driving; remote operations and mine-safety personnel retain fleet, access, and emergency authority.

Work that left the path
Human role before
Drivers held continuous tactical control of each truck.
Human role after
Workers supervise fleet operations, manage access and exceptions, and maintain autonomous equipment.
AI role
Autonomous navigation and fleet control for haul trucks in a constrained mine environment.
