    Codelco–CEA-Liten underground fleet electrification: design notes for mine engineers

    Codelco–CEA-Liten underground fleet electrification: design notes for mine engineers

    First reported on International Mining – News

    30 Second Briefing

    Codelco has signed a collaboration agreement with French research institute CEA-Liten (Laboratory for Innovation in New Energy Technologies and Nanomaterials) to develop technologies for electrifying underground mining fleets across its Chilean operations. The partnership will focus on powertrain electrification, high‑density battery systems and charging strategies suited to deep, high‑altitude block cave and panel cave mines, where ventilation demand and heat load are critical constraints. Outcomes are expected to inform future specifications for electric LHDs, trucks and support equipment, with direct implications for mine power distribution, ramp design and ventilation sizing.

    Technical Brief

    • Agreement formalised between Codelco and CEA-Liten specifically targets underground mobile equipment technologies.
    • CEA-Liten brings laboratory capability in new energy technologies and nanomaterials to the mining context.
    • Collaboration scope explicitly includes both study (concept/feasibility) and development (prototype/industrialisation) phases.
    • Decarbonisation of Codelco’s production processes is stated as a primary driver for the technology programme.
    • Partnership is framed as part of Codelco’s wider technological innovation strategy, not a standalone pilot.

    Our Take

    Codelco’s work with CEA-Liten on underground fleet electrification sits alongside its recent trials of XCMG all‑electric heavy‑duty trucks on the 700 km Chuquicamata–Mejillones route, signalling that the company is testing electrification across both underground and long-haul segments rather than in isolated pilots.

    Given Codelco’s recent scrutiny over copper output misclassification, visible partnerships with technical institutes like CEA-Liten on fleet decarbonisation can also help rebalance stakeholder narratives towards operational modernisation and ESG performance rather than purely governance issues.

    EPC Groupe–Sabodala contract: blasting capacity and slope control insights for engineers

    EPC Groupe, through EPC Mineex Sénégal, has secured a five-year explosives supply and services contract with Endeavour’s Sabodala gold mine in Senegal, valued at about €10 million per year at full run rate. The deal covers bulk explosives and blasting support for one of West Africa’s largest open-pit gold operations, signalling a step-up in local emulsion manufacturing, on-bench services and blast design capability. For mine planners and geotechnical teams, the contract points to stable high-volume blasting capacity, supporting consistent fragmentation and slope performance over the medium term.

    Haultrax HX Coach in FMS: operational coaching and dispatch insights for mine teams

    Haultrax is integrating its on-site operational coaching directly into its Fleet Management System with the launch of HX Coach at IMARC 2026. The module is designed to embed real-time operator guidance and training logic into haulage fleet dispatch, moving beyond traditional FMS reporting towards in-cab behavioural feedback and decision support. For mine operators, this signals a shift from separate coaching programmes to a software-native approach that can systematically influence truck and shovel performance at scale.

    IsaMill at 30: fine grinding efficiency lessons for concentrator engineers

    Glencore Technology is marking 30 years of the IsaMill fine grinding mill, first developed by Mount Isa Mines and NETZSCH to tackle complex, ultra-fine regrind duties in base metal circuits. The horizontal, high-intensity stirred mill has since been deployed in more than 130 installations globally, often replacing ball mills in the sub-20 µm range to cut specific energy consumption and increase throughput. Recent IsaMill developments focus on larger M-series units, improved ceramic media wear performance and integration with modern flotation and coarse particle recovery flowsheets.
