Sandvik–Subterra LS312 flameproof loader fleet: design and safety notes for coal mines
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Sandvik and Subterra Asset Solutions have delivered the first LS312 flameproof loaders in Australia as part of a 10-unit underground coal fleet developed through joint engineering and operator-led design. The EX d I Mb-certified loaders are tailored for gassy coal environments, with flameproof enclosures, intrinsically safe control systems and modifications based on service data from existing Sandvik fleets. For mine operators, the package signals a move towards standardised, OEM-backed flameproof fleets with local Subterra support for overhaul, compliance and lifecycle performance.
Technical Brief
- LS312 loaders are supplied in a 10-unit package fleet, enabling common spares and standardised procedures.
- Operator feedback from existing Sandvik coal fleets directly informed ergonomics, control layout and maintainability changes.
Our Take
The 10-unit LS312 flameproof loader fleet in Australia sits alongside Sandvik’s recent 27-unit underground fleet order for Orken LLP in Kazakhstan, signalling that Sandvik is scaling both specialised (flameproof) and bulk underground fleets across very different regulatory environments.
In our database of 1264 Mining stories, Sandvik appears frequently in underground equipment pieces, and the LS312 collaboration with Subterra in Australia reinforces its strategy of pairing OEM design with local service partners rather than relying on direct OEM presence alone.
Sandvik Australia’s Innovate Reconciliation Action Plan, which targets higher Aboriginal and Torres Strait Islander employment, suggests that local support and maintenance for fleets like the LS312 loaders could increasingly be delivered by a more diverse, community-linked workforce on Australian underground projects.
