    Cohda–Spectrum FiftyNine V2X at Oyu Tolgoi: safety and traffic insights for mine engineers

    First reported on International Mining – News

    30 Second Briefing

    Cohda Wireless and Spectrum FiftyNine are deploying compact V2X (Vehicle-to-Everything) modules at Rio Tinto’s Oyu Tolgoi underground mine in Mongolia to deliver real-time proximity awareness between heavy vehicles and personnel. The system integrates Cohda’s V2X software stack with Spectrum FiftyNine’s low-profile hardware, Roobuck cap lamps and Maptek’s mine planning and visualisation tools to create a unified situational awareness layer. For geotechnical and operations teams, this enables tighter traffic management in constrained headings and declines without relying solely on line-of-sight or radio voice calls.

    Technical Brief

    • Proximity alerts are automated, reducing dependence on manual radio protocols and operator line-of-sight judgement in headings.
    • Integration across vehicle hardware, personal lamps and planning software enables a single, mine-wide safety data layer.
    • Similar V2X stacks could be extended to geotechnical hazard zones, automatically warning crews approaching exclusion areas.

    Our Take

    Among the 2129 tag-matched pieces in our database, relatively few ‘Safety’ items focus on V2X-style communications, so deploying this at Oyu Tolgoi positions Cohda Wireless and partners at the more advanced end of mine traffic and collision-avoidance systems.

    Maptek’s presence in multiple ‘Projects’ and ‘Product’ stories in our Mining corpus suggests this collaboration could ease integration of V2X data into existing mine planning and fleet management workflows, rather than creating a standalone safety silo.

    Using Oyu Tolgoi as a proving ground gives Spectrum FiftyNine and Roobuck a high-profile reference site; in our coverage, technologies validated at large, complex operations tend to be fast-tracked for adoption in other tier-one mines seeking demonstrable safety gains.

    From reactive to predictive mining safety: data and sensing priorities for engineers

    Mining safety specialist David Coghlan, head of technology and product at TURCK, argues that connected sensing and control must shift mines from reactive alarms to predictive intervention as fleets, conveyors and fixed plant become more automated. He points to integrated proximity detection, real-time location and condition monitoring on mobile equipment, tied into site-wide networks, as the basis for predicting collision and entrapment risks rather than just logging incidents. For geotechnical and operations teams, this means designing safety systems around data quality, latency and interoperability, not just compliance with existing guarding and lock-out procedures.

    Evolution becomes Carnaby’s largest shareholder: M&A and project signals for mine planners

    Evolution Mining has become Carnaby Resources’ largest shareholder with a 13.7 per cent stake after acquiring the QIC Queensland Critical Minerals Fund’s ~37.9 million Carnaby shares as part of its proposed $213 million takeover. Evolution also issued about 2.6 million new shares to QIC, signalling continued use of scrip-based structures in Australian mid-tier M&A. For copper–gold project developers, the move points to stronger strategic interest from established producers in advanced exploration portfolios rather than greenfield assets.

    Develop’s Woodlawn drilling: 15-year mine life implications for planners and geotechs

    Develop Global’s latest underground drilling at the Woodlawn copper–zinc mine in New South Wales has returned intercepts grading up to 15.7 per cent copper equivalent (CuEq), supporting its Project DM15 plan to extend mine life from 10 to 15 years. The high-grade results, from step-out holes targeting depth extensions of existing lenses, suggest additional sulphide resources beyond the current reserve envelope. For mine planners and geotechs, this points to a longer stoping schedule, potential redesign of sequencing and backfill, and extended use of existing underground infrastructure.
