    Prairie Machine Flexiveyor MSHA approval: haulage design notes for coal engineers

    December 19, 2025|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    Prairie Machine’s Flexiveyor Continuous Haulage System has received MSHA certification from the US Mining Safety and Health Administration’s Approval and Certification Center, clearing it for use in regulated underground coal operations. The modular Flexiveyor is designed to provide continuous haulage between the mining face and section belt, reducing shuttle car traffic and associated congestion in development headings. Certification opens the US underground coal market to the system, giving mine engineers an additional compliant option for redesigning panel layouts and material flows around continuous haulage.

    Technical Brief

    • MSHA approval was issued by the dedicated Approval and Certification Center (A&CC) for mining equipment.

    Our Take

    With the IEA expecting US coal use to rebound in 2025 after years of decline, MSHA certification for equipment like Prairie Machine’s Flexiveyor positions it for retrofit and replacement cycles in ageing US underground coal fleets rather than just greenfield demand.

    Among the 393 Mining stories in our database, coal-linked items are a minority compared with battery metals, so MSHA-approved haulage systems stand out as one of the few growth niches tied to regulatory-driven upgrades rather than pure volume expansion.

    For US operators, deploying an MSHA-certified continuous haulage system on coal sections can shorten internal approval and procurement timelines, as safety-compliant OEM kit typically faces fewer hurdles from corporate risk committees and insurers than non-certified alternatives.

    BEUMER India MET City plant: logistics and design takeaways for conveyor engineers

    BEUMER Group has inaugurated a new INR 2 billion manufacturing facility at Reliance’s Model Economic Township (MET City) in Jhajjar, Haryana, marking a major expansion of its Indian material handling footprint. The high-tech plant will localise production of bulk handling systems and conveyor technology for mining and cement, reducing import dependence and lead times for large overland conveyors and loading systems. For project engineers, closer regional fabrication should simplify logistics, spares support and lifecycle service for high-capacity conveying installations across India and neighbouring markets.

    Epiroc’s Pit Viper: autonomous drilling lessons for mine planners and D&B engineers

    Epiroc’s Pit Viper blasthole drill, introduced 25 years ago, remains a flagship high‑capacity rig in large open pits, combining high power with flexible mast and hole configurations for production drilling. The platform has operated autonomously for the past decade, with fleets running driverless drill patterns and remote supervision from control centres rather than on‑bench cabins. For mine planners and drill‑and‑blast engineers, the Pit Viper’s long autonomous track record is a key reference point for integrating automated drilling into existing benches, patterns and safety envelopes.

    Eldorado Gold’s Lamaque BEVs: ventilation and haulage design notes for engineers

    Eldorado Gold is expanding electrified underground load-and-haul at the Lamaque Complex in Val-d’Or, Québec, with an order for 10 Sandvik battery-electric vehicles and 10 charging systems, including five TH550B 50‑t trucks and five Toro LH518iB loaders. The first two TH550B trucks were delivered in October, with the remaining three trucks and five loaders to follow, supporting a fully electric primary haulage fleet in key production areas. For mine planners and ventilation engineers, the BEVs are expected to cut diesel emissions and heat load, enabling tighter development in deeper zones.
