    Darma Henwa’s 10 new Liebherr units: pit advance and stability notes for mine teams

    September 9, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    Darma Henwa has expanded its fleet with 10 new Liebherr machines to support increased overburden and coal production at Kaltim Prima Coal’s Bengalon mine in East Kalimantan and Arutmin’s Kintap mine in South Kalimantan. The additional units, likely including large hydraulic excavators and ultra-class mining trucks typical of Liebherr’s Indonesian deployments, are being deployed to a new pit at Bengalon and to meet higher production targets at Kintap. For mine planners and geotechnical teams, the larger fleet implies higher stripping rates, faster pit advance and tighter haul road and dump stability requirements.

    Technical Brief

    • Liebherr’s supply supports Darma Henwa’s role as an integrated mining service provider rather than owner-operator.
    • Fleet standardisation around Liebherr at both sites simplifies maintenance planning and critical spares stocking across Kalimantan.
    • For mine geotechnical teams, a single OEM across pits can streamline truck–shovel match assumptions and haul road design envelopes.

    Our Take

    Our database shows Darma Henwa already running Tonly wide-body trucks at Kaltim Prima Coal’s Sangatta operation, so adding 10 Liebherr units suggests the contractor is deliberately diversifying OEMs rather than standardising on a single truck supplier in East Kalimantan.

    The recent five‑year coal mining services award to PT DH Kontraktama Batubara at Pulau Laut, involving XCMG equipment, indicates Darma Henwa is spreading capex and fleet risk across multiple Chinese and European brands, which can give it leverage in pricing and parts support negotiations for Bengalon and Kintap.

    Tru-Trac conveyor belt and thermal scanning: reliability lessons for mine engineers

    Advanced thermal scanning combined with modern belt scanning is being deployed by Tru-Trac to detect hotspots, misalignment and structural defects on high-capacity mining conveyors before they escalate into catastrophic failures. David Pereira, Head of Sales, points to continuous infrared monitoring of idlers, pulleys and drive stations, integrated with belt rip and splice detection systems, to trigger early interventions rather than reactive shutdowns. For engineers, the key shift is moving condition monitoring from periodic manual inspections to automated, full-length conveyor health scans that can be trended and alarmed in real time.

    Weir comminution efficiency gains: design and control lessons for mine engineers

    Technology-led optimisation of comminution circuits can deliver immediate, material efficiency gains when applied with tight process control, argues JD Singleton, Comminution Director for EMEA at Weir. Singleton links precision deployment of tools such as high-pressure grinding rolls, advanced process control and real-time ore characterisation to lower specific energy consumption and reduced CO₂ per tonne milled. He stresses that disciplined implementation and continuous performance tracking are essential if mines are to meet carbon targets without escalating unit operating costs.

    Eldorado Gold’s first Skouries concentrate: ramp-up and design notes for engineers

    Eldorado Gold has produced first copper-gold concentrate from its wholly owned Skouries project in northern Greece, signalling the shift from construction to operational ramp-up at this long-delayed porphyry deposit. The company is targeting commercial production in the December quarter of 2026, with Skouries designed as a combined open-pit and underground operation using conventional crushing, grinding and flotation to generate a high-grade copper-gold concentrate. Early plant performance and de-bottlenecking over the next two years will be critical for validating throughput, recovery assumptions and tailings management strategies.
