    Chuquicamata ST10000 belt replacement: design and maintenance notes for engineers

    Chuquicamata ST10000 belt replacement: design and maintenance notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    ContiTech has completed the first replacement of an ST10000 steel-cable conveyor belt at Codelco’s Chuquicamata copper mine in Chile, one of the largest uphill tunnel conveyor installations in global mining. The ST10000 belt, previously pioneering for high-tension, steep-gradient underground haulage at Chuquicamata, required complex change-out logistics in confined tunnel conditions and precise splice management for ultra-high-strength cords. The project confirms that life-cycle replacement of ST10000-class belts is technically viable, which will influence long-haul conveyor design and maintenance planning for deep and block cave operations.

    Technical Brief

    • Steel-cord construction required precise cord alignment and constant tension control during each hot vulcanised splice.
    • Uphill tunnel geometry constrained reel diameters and belt mass, forcing staged belt pulling and reeling.
    • Confined underground installation limited crane access, so belt handling relied on winches, sleds and specialised turning frames.
    • Transition zones and curve sections needed careful tracking control to avoid edge damage on the ultra-stiff belt.
    • Integration with existing drive stations and take-up systems demanded recalibration of tension set-points after replacement.
    • Replacement validates long-haul, high-tension steel-cord conveyors as a life-cycle alternative to deep truck haulage.

    Our Take

    Codelco’s work at the Chuquicamata copper mine with an ST10000 conveyor belt sits alongside other recent high-capex infrastructure moves in Chile, such as Freeport-McMoRan’s proposed $7.5 billion El Abra expansion, signalling sustained long-life investment in the country’s copper corridor rather than short-term debottlenecking.

    Our database shows multiple recent Codelco items pairing heavy-duty fixed infrastructure with fleet modernisation, from Sandvik Toro LH515i loaders at Chuquicamata Underground to the SANY electric haul truck pilot, suggesting the miner is methodically upgrading both bulk materials handling and mobile equipment to cut operating risk and emissions.

    With Chile’s government targeting a 30% reduction in mining permit processing times to unlock over $100 billion in investment, high-spec assets like ST10000 conveyor systems at Chuquicamata are likely to become reference points for technical standards on future large copper project approvals in the country.

    Bradken SmartRoller™ for excavators: reliability and maintenance insights for engineers

    Bradken has launched Bradken SmartRoller™, a digital system that continuously monitors excavator undercarriage roller temperature in real time via remote sensing. By tracking temperature trends as a proxy for wear progression and issuing early alerts, the system allows operators to schedule proactive roller replacement rather than waiting for failure. The approach targets higher excavator uptime, more stable undercarriage performance and lower lifecycle costs for high-hour fleets in abrasive conditions.

    MAV2205 shaft–hub locking devices: bending load insights for conveyor engineers

    MAV2205 shaft–hub locking devices are being engineered specifically for mining conveyor pulleys where high belt tensions and heavily loaded drive or bend drums impose severe bending loads on the pulley shaft, not just torque. By clamping concentrically along the shaft–hub interface, the unit spreads bending stresses more evenly than traditional keyed or welded connections, reducing local stress concentrations that initiate fatigue cracks. For designers and maintenance teams, this supports longer pulley service life, fewer unplanned shutdowns and more predictable performance in high-tension conveyor duty.

    Regis wins McPhillamys court challenge: approvals reset and design notes for mine planners

    Regis Resources has won a Federal Court challenge over its McPhillamys gold project in New South Wales, with the court declaring invalid a Commonwealth heritage protection declaration that had halted development. The 14 October ruling sends the project back to federal Environment Minister Murray Watt for redetermination, reopening the approvals pathway for the planned open-pit operation near Blayney. Geotechnical and mine planning teams can now resume work on pit design, waste rock emplacement and associated infrastructure, pending any new heritage conditions.
