    Dyno Nobel Navus handheld blaster: design and safety notes for drill‑and‑blast teams

    Dyno Nobel Navus handheld blaster: design and safety notes for drill‑and‑blast teams

    First reported on International Mining – News

    30 Second Briefing

    Dyno Nobel has launched the Navus handheld blaster, a 600 g electronic initiation device designed to trigger blasts via up to 2,500 m of harness wire anywhere on site. The unit extends the company’s electronic initiation range beyond fixed blast boxes, giving engineers more flexibility in complex pit geometries, underground headings and perimeter stand-off locations. For drill-and-blast teams, the compact form factor and long wire support enable wider separation between charge areas and firing points without adding extra infrastructure.

    Technical Brief

    • Handheld format reduces reliance on fixed firing lines, lowering exposure around traditional blast boxes.
    • Portable unit supports relocating firing points to better shield crews from flyrock and overpressure zones.
    • Electronic initiation compatibility enables precise timing control, improving vibration management near sensitive infrastructure.
    • Reduced hardware footprint simplifies blast site housekeeping, aiding compliance with exclusion-zone and clearance protocols.
    • For multi-bench or staggered headings, mobile initiation supports more flexible evacuation and line-of-sight safety planning.

    Our Take

    Within the 1,398 tag-matched pieces in our database, relatively few ‘Product’ and ‘Safety’ items focus on blasting hardware, so Dyno Nobel’s Navus unit stands out as part of a smaller subset of operational-safety tech rather than project-level risk stories.

    A 600 g handheld blaster suggests Dyno Nobel is targeting field crews who are already burdened with radios, tablets and PPE; in practice this kind of weight and form factor tends to improve compliance with electronic initiation protocols compared with bulkier legacy controllers.

    Across the 707 Mining stories, most safety coverage is incident- or regulation-led, so a proactive product launch by Dyno Nobel signals that OEMs are increasingly trying to differentiate through ergonomic and human-factor design rather than only through explosive performance or cost per blast hole.

    Volvo’s right-sized rigid mining trucks: fleet and haul road insights for engineers

    Volvo Construction Equipment is pushing to expand its share of the smaller rigid mining truck segment, challenging Caterpillar’s 777/775 and Komatsu’s HD785/HD685 with its rigid haulers built in Motherwell, Scotland. The “right-sized” Volvo units target mines where ultraclass trucks are impractical, focusing on optimised payload-to-weight ratios and shorter cycle times on tighter haul roads. For operators, the main implications are alternative fleet configurations in the 60–100 t class and potential lifecycle cost competition in brownfield pits constrained by ramp geometry and crusher layouts.

    Kazatomprom’s value-over-volume uranium strategy: key points for mine planners

    Kazakhstan’s state-controlled Kazatomprom, which produces most of the country’s roughly 40% share of global uranium supply via low-cost in-situ recovery, is doubling down on its “value over volume” strategy, refusing to flood the market despite a sevenfold rise in its London-listed share price since 2018. CEO Meirzhan Yussupov says any move further down the fuel cycle, including ambitions for domestic enrichment, must clear strict payback, IRR and NPV hurdles and comply with non-proliferation constraints. He also positions Kazatomprom’s dual listing in London and on the common-law-governed Astana International Exchange as a proof point for Kazakhstan’s investor protections.

    Kazatomprom and uranium markets: supply, logistics and project signals for engineers

    Kazatomprom CEO Meirzhan Yussupov says the company will maintain its “value over volume” strategy, limiting output growth to about 10% year-on-year rather than chasing market share, despite surging nuclear demand from China, India’s 100 GW-by-2047 SHANTI targets and AI-driven data centres. He confirms Kazakhstan already mines, processes and fabricates fuel assemblies for export to China, and is now evaluating an in-country conversion plant using newly acquired technology, with investment contingent on IRR, NPV and payback. Yussupov notes up to roughly 60–65% of Western deliveries have recently moved via the Trans-Caspian Middle Corridor, while transit through Russia to St Petersburg remains legally available as Kazakh uranium is not covered by Russian-origin bans.
