Autonomous Haulage & Drilling

Driverless trucks and drills now move billions of tonnes per year. Learn how autonomous haulage systems (AHS) work — GNSS positioning, perception, path planning, fleet control and safety zones — their productivity and safety benefits, operating-hour gains, and implementation challenges.

Since 2008, autonomous trucks have operated in the Pilbara (Australia) and later in Chile, Canada and elsewhere. Without shift changes, breaks and fatigue, autonomous trucks can operate ≈ 1000–1500 more hours per year, with smoother driving that saves tyres and fuel, and people are removed from the highest-risk zone.

An analogy

An autonomous fleet is like a train network without drivers: a central controller assigns routes and permissions, and each vehicle follows its path while sensors watch for obstacles.

How AHS works

Each truck has high-precision GNSS, inertial navigation, radar/LiDAR obstacle detection and drive-by-wire controls. A central fleet management system plans paths, assigns loading and dumping points, and grants 'permission areas' so trucks never conflict.

Benefits

More operating hours (no shift changes, breaks), consistent speeds and cornering, reduced tyre wear and fuel, fewer incidents, and fewer people exposed to haul roads. Reported productivity gains are 15–30 %.

Challenges

Mixed fleets with manned vehicles, reliable wireless networks (LTE/5G), road and dump discipline, cybersecurity, workforce transition and retraining, and higher up-front cost.

Autonomous drilling and beyond

Autonomous drills follow blast plans precisely with MWD; autonomous dozers and water carts, automated trains (AutoHaul), and underground autonomous LHDs extend automation across the value chain.

Formulas

• Annual tonnes per truck: T_truck = H_op × P
• Trucks required: N = T / (H_op × P)
• Productivity gain: Gain = H_op,auto / H_op,manned − 1

Worked example: Operating-hour gain

Given: Manned truck 5500 h/yr, autonomous 7000 h/yr

Find: Productivity gain.

• Gain = 7000/5500 − 1 = 27 %

Answer: ≈ 27 % more tonnes per truck

Worked example: Fleet size

Given: 20 manned trucks at 5500 h; Same tonnage with AHS at 7000 h

Find: Autonomous trucks needed.

• N = 20 × 5500/7000 = 15.7

Answer: 16 trucks instead of 20

Common mistakes

• Wrong: Automating a poorly run operation. — Right: Fix road, dump and loading discipline first.
• Wrong: Ignoring the workforce. — Right: Plan retraining and new roles (controllers, technicians).

Applications

• Iron ore: Large AHS fleets in the Pilbara.
• Copper and oil sands: AHS in Chile and Canada.
• Drilling: Autonomous blasthole drills.

Key takeaways

• AHS = GNSS + perception + fleet control.
• More hours → fewer trucks.
• Safety: people out of haul zones.
• Networks and people are key.

Going further

• Interoperability: Open standards for mixed-OEM autonomy (ISO 17757).
• Cybersecurity: Protecting autonomy networks.
• Human-machine interaction: Safe interaction zones and procedures.
