    Malabar’s Maxwell longwall start-up: design and scheduling notes for mine engineers

    First reported on International Mining – News

    30 Second Briefing

    Malabar Resources has completed the first full shears of coal from the longwall at its Maxwell Underground mine in the Hunter Valley, New South Wales, initiating production at what is planned to be the region’s newest and largest long-life longwall operation. The project, developed under New South Wales planning approval, transitions Maxwell from development drivage to longwall extraction using a high-capacity shearer and shield supports. This step moves the mine towards sustained longwall panel production, with implications for regional coal supply, ventilation design, strata control and long-term equipment scheduling.

    Technical Brief

    • Transition to longwall implies full commissioning of face conveyor, stage loader and outbye belt system.
    • First full shears confirm coal cutting parameters and initial face equipment synchronisation under production conditions.
    • Commencement of longwalling triggers ramp‑up of gas drainage, ventilation balancing and goaf sealing strategies.
    • Strata control regime now shifts from development bolting patterns to longwall-specific shield loading and convergence monitoring.
    • Start-up phase will refine production scheduling, maintenance intervals and spares inventory for high‑duty longwall components.
    • Regional power and water demand profiles change as continuous longwall systems displace intermittent development equipment usage.

    Our Take

    Given the Hunter Valley’s dense cluster of existing coal operations, the move to longwall mining at Maxwell Underground likely intensifies competition for skilled underground labour and contractor capacity in New South Wales, which our database shows is already under pressure from multiple concurrent mining projects in the region.

    Sandvik’s SEK 175m LKAB Malmberget order: flowsheet notes for plant engineers

    Sandvik has secured a SEK 175 million order from LKAB to supply crushing and screening equipment for the new iron ore sorting plant at Malmberget, booked in Q2 2026. The package includes cone crushers, double-deck screens and vibrating feeders, forming the core of the primary and secondary sizing circuit. For plant designers and process engineers, the deal signals continued reliance on high-capacity, fixed crushing lines for Nordic underground iron ore operations rather than modular or fully mobile alternatives.

    Eurasian Resources–BAUER vertical bauxite mining: design and planning notes for engineers

    Eurasian Resources Group’s Aluminium of Kazakhstan unit has commissioned BAUER rotary drilling equipment at open pit No. 4 of the Vostochno-Ayatskoye Krasno-Oktyabrskoye bauxite mine to trial what is described as the world’s first vertical bauxite extraction project. The system uses vertical rotary drilling rather than conventional bench blasting and truck–shovel methods, aiming to access deeper ore zones within the existing pit footprint. For geotechnical and mine planners, the approach could alter pit slope design, drilling patterns and ground support requirements if adopted at scale.

    ExxonMobil–Teck renewable diesel deal: haul fleet implications for mine operators

    ExxonMobil has finalised a supply agreement with Teck for Esso Ethos+ Renewable Diesel R100 in Canada and completed the first delivery to Teck’s Highland Valley Copper (HVC) operations in British Columbia. The 100% renewable diesel will be produced by Imperial Oil’s Strathcona refinery, which is being upgraded to manufacture bio-based fuels for heavy-duty applications such as mine haul trucks and support fleets. For mine operators, the deal signals growing availability of drop-in low-carbon fuels compatible with existing diesel engines and fuel infrastructure.
