    The reliability issue miners overlooked: maintenance lessons for fleet engineers

    The reliability issue miners overlooked: maintenance lessons for fleet engineers

    First reported on Australian Mining

    30 Second Briefing

    Underground hard-rock mines are seeing development jumbo productivity eroded by repetitive maintenance on feed rail ropes, which are being replaced at increasingly short intervals long before outright failure. Crews are adapting work patterns around these stoppages rather than addressing the root cause, normalising frequent shutdowns and masking the true reliability problem in shift reports and KPIs. The case signals that reliability engineering in mobile fleets must target chronic, sub-failure component issues – such as rope wear mechanisms and lubrication regimes – not just catastrophic breakdowns.

    Technical Brief

    • Underground mining operations rarely lose efficiency overnight, but repetitive maintenance behaviour can quietly erode productivity long before equipment ever fails.
    • Over time, crews adapt around the disruption instead of eliminating it.

    Our Take

    Across our database of 1185 Mining stories, MASPRO appears mainly in the context of uptime and component availability, so framing reliability as a safety issue in Australia signals that operators are starting to treat parts logistics as part of their critical risk controls rather than just maintenance cost.

    The related piece on MASPRO’s work at Kingston Resources’ Mineral Hill operation shows that reliability-focused component strategies are being trialled on live Australian projects, giving other sites a reference point for quantifying how improved parts resilience can reduce both unplanned stoppages and exposure hours around heavy plant interventions.

    Sandvik underground fleet at Kamoa-Kakula: haulage and maintenance lens for engineers

    Sandvik has secured an order from Kamoa Copper SA for 19 Toro® underground trucks and loaders for the Kamoa-Kakula Copper Complex in the Democratic Republic of the Congo, taking the site’s Sandvik underground fleet to more than 100 units. The equipment will support one of the world’s largest underground Sandvik fleets at a single mine, operated by the Ivanhoe Mines–Zijin Mining joint venture. For engineers, the scale signals sustained high-volume, trackless underground haulage and significant long-term demand for OEM parts, maintenance capacity, and fleet management systems.

    Metso Durarok™ primary sizer at Yenipazar mine: design and throughput notes for engineers

    Metso has secured a €25 million order from Aldridge Mineral Madencilik A.Ş., part of CVK Mining, to supply key minerals processing equipment for the Yenipazar polymetallic mine in Türkiye, including one of its first Durarok™ primary sizers. The package, booked in Metso’s Minerals segment for 2026, will support primary crushing and downstream processing for a deposit containing multiple base and precious metals. For engineers, early adoption of the Durarok™ sizer at Yenipazar will be a reference case for hard-rock primary sizing performance in Turkish conditions.

    Volvo Autona / earth autonomous haulage: key takeaways for mine planners

    Volvo Autonomous Solutions has launched Autona / earth, a commercial autonomous haulage system for mines and quarries built around an autonomous Volvo FH truck and an in-house developed virtual driver. The package is delivered as Transport-as-a-Service, with Volvo providing the vehicle automation stack, site infrastructure, operational support and maintenance rather than selling trucks outright. The system is designed to plug into existing mine haulage operations, signalling a shift towards OEM-managed autonomous fleets where OEMs assume more responsibility for uptime and performance.
