    Tonly TLE120 at Wengfu Phosphate Mine: haulage design notes for engineers

    Tonly TLE120 at Wengfu Phosphate Mine: haulage design notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    Tonly Heavy Industries has delivered a fleet of 75 t-class TLE120 battery electric wide-body dump trucks to the Baiyan open-pit mining area of Wengfu Phosphate Mine in Guizhou Province, China. The trucks will operate on short-haul, high-frequency phosphate ore routes at the boundary of Weng’an County and Fuquan City, where haul profiles and predictable duty cycles favour battery swapping and regenerative braking. For mine planners and haulage engineers, the deployment signals growing Chinese adoption of large battery-electric trucks in high-volume open-pit phosphate operations.

    Technical Brief

    • TLE120 units are wide-body dump trucks in the 75 t payload class, targeting high-volume overburden/ore haulage.
    • Deployment is tied to a modernised open-pit phosphate layout, implying relatively fixed, repeatable haul profiles.

    Our Take

    Tonly Heavy Industries’ delivery of 75 t-class battery electric trucks into the Wengfu Phosphate Mine aligns with its broader push into low‑carbon haulage, as seen in its 2026 Overseas Customer Festival line‑up of “green” mining trucks under China’s dual‑carbon policy, signalling that phosphate operations are now being used as real‑world reference sites for this platform.

    The 75 t-class TLE120 deployment in China complements Tonly’s 70 t-class DTE95 battery electric trials in Germany and hybrid 91 t-class trucks in Brazil, suggesting the company is methodically proving its wide‑body electric and hybrid haulage across multiple payload classes and geologies before larger‑scale international roll‑outs.

    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.
