Inside Australia’s Autonomous Mines: The Electronics Powering the Shift

Australia’s mining sector is undergoing a major technological transformation.

Across iron ore, coal and critical minerals operations, automation is redefining how mines are planned, operated and maintained. Autonomous haul trucks navigate pit roads without drivers. Underground longwall systems adjust in real time with minimal human intervention. Sensors monitor equipment, environmental conditions and worker safety around the clock.

Behind these advancements is a powerful but often unseen force: advanced electronics. As mines get smarter, the electronics powering them must be tougher, more precise and more reliable than ever.

Mining has long been one of Australia’s most hazardous industries. Equipment failures, collapses, tyre blowouts and exposure to explosive atmospheres put workers at serious risk. Autonomous systems reduce this exposure by relocating operators to remote control rooms and shifting the risk to engineered systems.

Automation delivers clear advantages:

• Safer operations in high-risk environments
• Consistent, data-driven productivity
• Reduced downtime through predictive maintenance
• Real-time operational insight
• Optimised asset utilisation and lower operating costs

Above all, safety is the main driver of autonomous mining.

Autonomous mining relies on an interconnected ecosystem of electronics:

• Sensors and Data Acquisition: Lidar, laser scanners and environmental monitors gather intelligence for autonomous decision-making.
• Embedded Control Systems: These controllers process incoming data and execute precise mechanical actions e.g steering haul trucks and adjusting longwall shearers.
• Communication Modules: Reliable networks enable machine-to-machine and machine-to-operator data exchange.
• Ruggedised Power and PCB Assemblies: High-reliability boards and industrial-grade enclosures survive extreme heat, dust, vibration and moisture.

Without high-quality electronics manufacturing, automation cannot progress beyond prototypes. Performance and durability define success.

Extreme heat. Heavy vibration. Dust. Moisture. Explosive atmospheres. Mining electronics must perform flawlessly where human exposure is unsafe.

Modern systems overcome these challenges through:

• Ruggedised PCB layouts and reinforced soldering
• Conformal coating and environmental sealing
• Industrial-grade, high-temperature components
• Intrinsically safe designs meeting mining standards

These electronics are engineered for endurance, delivering uninterrupted performance over long operational lifecycles. Often placed in remote locations where maintenance access is limited, the reliability of these systems is essential.

Hetech has supported this transition to increased autonomy through its many alliances within the Mining industry. 

In partnership with Quantam and the CSIRO, we manufactured the rugged electronics behind the Longwall Automation System and ExScan 3D laser scanner, from intrinsically safe underground sensing to precision control.

Through our work with Decoda, Hetech delivered the electronics powering the RockAware™ system, providing real-time tyre and haul road monitoring for heavy haul fleets. By applying Design for Manufacturing (DFM) principles to optimise the production of the electronics for repeatable, we helped transition these systems from prototype to industry ready systems.
