    Motion roof support rebuilds: integrated project lessons for mine engineers

    Motion roof support rebuilds: integrated project lessons for mine engineers

    First reported on Australian Mining

    30 Second Briefing

    A longwall mine roof support system requiring a complete overhaul was rebuilt by Motion using its integrated national network to deliver a fully compliant, site-ready package. The project involved complete strip-down, inspection and refurbishment of hydraulic legs, canopies and base units, with all critical components reconditioned or replaced to OEM specifications and certified to relevant Australian Standards. Centralised project management and in-house machining, hydraulics and testing shortened turnaround and reduced interface risk compared with multi-vendor rebuilds, offering a template for future large-scale support refurbishments.

    Technical Brief

    • Motion coordinated strip-out, rebuild and reinstallation through a single project team to maintain traceable accountability.
    • All hydraulic legs were dismantled to component level, enabling detailed inspection of bores, rods and seals.
    • In-house machining of worn pins, bushes and clevises reduced reliance on third-party workshops and transport interfaces.
    • Pressure testing of hydraulic circuits was conducted under controlled workshop conditions before dispatch to the mine.
    • Canopy and base structures underwent non-destructive testing to identify fatigue cracking prior to any weld repairs.
    • Replacement parts were sourced through Motion’s national inventory system, limiting substitution risk and ensuring material traceability.
    • Centralised documentation captured inspection records, test certificates and conformance reports into a single safety file for site acceptance.
    • Single-vendor rebuilds like this reduce coordination gaps that often lead to incompatible settings or undocumented safety-critical changes.

    Our Take

    Motion’s repeated appearance in recent Australian Mining pieces – from upgraded workshops in Mackay, Rutherford and Perth (22 Feb 2026) to consolidated WA fluid power services (13 Jan 2026) – signals a deliberate push to be a full-service maintenance partner for Australian underground and surface operations, rather than just a components supplier.

    The focus on hydraulic and mechanical reliability in the Exitflex hose and Fenner coupling articles linked to Motion suggests that any roof support rebuild programme in Australia can likely be integrated with broader drivetrain and fluid power upgrades, reducing unplanned downtime across multiple systems rather than treating roof supports as a standalone asset class.

    Within our Mining category coverage, Motion is one of the more frequently recurring service brands in safety- and product-tagged pieces, indicating that Australian operators are increasingly leaning on third-party specialists for critical support equipment overhauls instead of relying solely on in-house workshops.

    Scope Systems cyber attack: resilience and risk lessons for mining IT teams

    A ransomware attack on Perth-based Scope Systems’ Pronto Xi ERP cloud stack disrupted dozens of mining customers, including Northern Star Resources and Evolution Mining, in what MM‑ISAC’s Rob Labbe calls the broadest single third‑party cyber event the sector has seen. Scope says client servers were restored from backups and not directly accessed, but admits internal data was exfiltrated and has not disclosed the attack vector, raising questions about visibility at hypervisor, storage and backup layers. The incident spotlights how multi‑tenant vCenter/ESXi environments, VM cloning and snapshot abuse—already used by groups like Akira—could expose integrated exploration, production and maintenance data across more than 400 Pronto Xi‑reliant mining operations.

    Newmont’s Red Chris underground expansion: block cave design and capex notes for engineers

    Newmont’s Red Chris mine in British Columbia has secured an amended Environmental Assessment Certificate and Mines Act permit, allowing a shift from open-pit to underground block caving and extending operations into the mid-2040s. The copper-gold porphyry deposit in the Golden Triangle hosts an estimated 20 million oz of gold and 13 billion lb of copper, with the block cave expected to lift Canada’s copper output by about 15%. The project entails several billion dollars in capital, around 1,800 construction jobs and roughly 1,500 operating roles at peak.

    Goldman cuts gold price forecast to US$4,900: planning notes for mine projects

    Goldman Sachs has cut its end‑2026 gold price forecast by US$500/oz to US$4,900/oz after the US Federal Reserve, under new chair Kevin Warsh, signalled a hawkish shift that has pushed market-implied December rate hike odds to 87%. Spot gold has already fallen to about US$4,100/oz, down 27% from its near‑US$5,600/oz January peak, with three consecutive monthly losses between March and May and a 4% year‑to‑date decline. Goldman warns a 2026 year‑end target as low as US$4,400/oz is possible if rates rise, partly offset by ongoing central‑bank buying of roughly 50 tonnes/month this year and 40 tonnes/month next year.
