    Epiroc’s Automatic Bit Changer on large DTH drills: safety and uptime notes for mines

    September 2, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    Epiroc is extending its Automatic Bit Changer (ABC), first deployed on large Pit Viper rotary drills in 2022, to its range of large down-the-hole (DTH) crawler rigs. The system automates drill bit change-out, removing manual handling at the drill string and reducing exposure around the rotary head and deck. Mines can expect shorter non-productive time during bit swaps and lower operator workload, particularly on high‑metreage production benches where frequent bit changes are required.

    Technical Brief

    • Automated bit handling removes manual intervention at the drill head, directly reducing dropped-object and pinch-point exposure.
    • Remote-controlled change-out keeps personnel off the drill deck during bit swaps, improving compliance with exclusion-zone rules.
    • Consistent, mechanised bit installation reduces risk of mis-threading or under-torqued joints that can lead to string failures.
    • Lower physical workload for drill crews supports fatigue management programmes and reduces musculoskeletal injury risk.
    • Wider adoption on large production rigs could influence future mine standards for bit-handling automation on high-risk benches.

    Our Take

    The safety-tagged nature of this product aligns with other recent Epiroc coverage where automation (for example, RCT – Powered by Epiroc’s AutoNav systems on loaders) is being used to remove personnel from high‑exposure tasks, suggesting mine operators are more willing to pay for features that directly reduce manual interaction with drilling tools.

    Sandvik IEC 62443-4-1 ML3: cybersecurity implications for intelligent mines

    Sandvik has secured IEC 62443-4-1 Maturity Level 3 certification for its secure product development lifecycle, making it one of the first mining OEMs to reach this cybersecurity benchmark. The independently audited ML3 rating confirms that threat modelling, secure coding, vulnerability management and patch processes are systematically built into the design and maintenance of its intelligent mining equipment and digital systems. For mines deploying connected fleets, autonomous loaders and remote drilling rigs, this signals stronger protection against cyber intrusion at both equipment and control-system level.

    BME’s VIPERTRON electronic initiation system: design and timing notes for mine engineers

    BME has launched the VIPERTRON electronic initiation system, a lightweight, compact blasting solution designed for agile deployment in quarries and surface mines using robust radio-frequency communication between field units and the blasting control. The system targets operations still using NONEL by offering tighter timing accuracy and more consistent blast performance, while maintaining simple, portable hardware for crews working in constrained benches and multiple small shots. For engineers, the key shift is towards electronic timing control without the complexity and bulk of traditional wired electronic detonator systems.

    Brightstar’s Laverton expansion corridor: mine planning and haulage lens for engineers

    Brightstar Resources has secured five exploration licences comprising Panther Metals’ Mikado project around its new Laverton processing plant in Western Australia under a 100 per cent binding tenement sale agreement. The deal consolidates tenure immediately adjacent to the planned processing hub, giving Brightstar direct control over near-plant feed sources rather than relying on satellite ore trucking. For mine planners and geotechs, the enlarged footprint enables integrated pit design, waste dump siting and haulage optimisation across a contiguous land package.
