    Hexagon Vehicle Intervention System Level 9: TRL4 test insights for mine safety engineers

    March 25, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    Hexagon’s latest-generation Vehicle Intervention System has become the first and only open-pit Level 9 collision avoidance solution to pass the University of Pretoria’s Collision Prevention System Technology Readiness Level 4 test. The UP TRL4 protocol subjects systems to controlled, repeatable collision scenarios to verify automatic braking and intervention performance on large haul trucks and other heavy mobile equipment. The result signals that VIS can meet South Africa’s Level 9 requirement for automated vehicle intervention, moving beyond advisory-only Level 7/8 CPS deployments in open-pit mines.

    Technical Brief

    • Successful TRL4 outcome is likely to accelerate regulator and operator adoption of mandatory Level 9 CPS.

    Our Take

    Achieving a Technology Readiness Level 4 test on a Level 9 Vehicle Intervention System positions Hexagon at the more experimental end of the 2,000+ product- and safety-tagged mining items in our database, where most operational collision-avoidance deployments are still at lower intervention levels or lower TRLs.

    The University of Pretoria’s role in the TRL4 collision prevention testing echoes Hexagon’s earlier collaboration with Montana Technological University on underground training, suggesting the company prefers to validate high-criticality safety systems through academic test beds before large-scale mine roll-out.

    XCMG electric fleets in Australian mines: design and cost shifts for planners

    XCMG is deploying battery-electric heavy mobile equipment in Australian mines, including large-capacity haul trucks and loaders designed for zero on-site emissions and high-duty cycles. The Chinese OEM is pairing these units with fast-charging infrastructure and modular battery packs to minimise downtime in continuous operations typical of Pilbara-scale iron ore and hard-rock sites. For mine planners and maintenance teams, the shift to electric fleets changes pit ventilation requirements, power reticulation design, and lifecycle cost models compared with conventional diesel equipment.

    NSW targets fuel distribution to support miners: continuity and risk notes for ops teams

    New South Wales is prioritising diesel and petrol deliveries to mining operations alongside other critical sectors as it manages constrained fuel supplies across the state. The policy aims to keep large open-cut and underground fleets, fixed plant and rail haulage operating, with fuel allocation coordinated through major distributors rather than ad hoc site-by-site deals. Mine operators are being asked to refine contingency plans, including reduced non-essential equipment use and tighter fuel inventory monitoring, to avoid production stoppages if supply tightens further.

    Johnson Range gold upgrade: mine design and M&A takeaways for WA project teams

    Forrestania Resources has confirmed a 103,500-ounce gold resource at the Johnson Range project in Western Australia, strengthening its case to complete the acquisition from Auris Minerals. The resource upgrade, reported in ounces rather than just grade–tonnage estimates, gives clearer backing for mine planning, pit optimisation and potential toll-treatment scenarios typical for small to mid-scale WA gold operations. For geotechs and miners, the defined inventory sharpens decisions on drilling density, geotechnical pit design and whether to justify further step-out exploration along strike.
