    Sandvik HPA20 resin pump: control, bond quality and safety insights for engineers

    March 16, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    Sandvik has launched the HPA20 (Hydraulic Power Automatic) injection pump as a next-generation system for resin-based ground support in hard-rock mining and civil works, combining intelligent automation with a modular, flexible architecture for underground use. The unit automates resin dosing and injection cycles, aiming to improve bond quality and consistency in rockbolts and cable bolts while reducing operator exposure at the face. For geotechnical and ground support teams, the key change is tighter control of resin volumes and timing, supporting more predictable load transfer and ground behaviour.

    Technical Brief

    • For other underground projects, similar automated dosing and remote operation could help standardise resin QA/QC procedures.

    Our Take

    Sandvik’s HPA20 launch sits alongside a cluster of recent Sandvik equipment roll-outs in our database – from the MC431 continuous miner to Ranger DX1010i drill rigs – signalling a push to offer more integrated, OEM‑supplied solutions across both development and support functions underground.

    Within the 2,071 tag‑matched pieces on Projects/Product/Safety, Sandvik appears frequently as an equipment supplier, which suggests that mines adopting the HPA20 resin injection pump are likely to find it easier to standardise maintenance, training and spares with other Sandvik fleets already on site.

    For underground operators, pairing a dedicated resin injection system like the HPA20 with Sandvik’s newer continuous miners (such as the MC431 referenced in our coverage) could enable tighter control of ground support cycles, reducing exposure time at the face and making it easier to document compliance with ground control management plans.

    Ausenco’s Ikkari gold Feasibility Study: design and risk notes for mine engineers

    Ausenco has secured the contract to lead the Feasibility Study for Rupert Exploration Finland Oy’s Ikkari gold project, a grassroots discovery made in 2020 and located about 45 km from Sodankylä in Lapland. The work follows completion of a Pre-Feasibility Study and will refine mine design, processing flowsheet and infrastructure options for a greenfield operation in Arctic conditions. Outcomes will be critical for geotechnical design in sub-Arctic ground, tailings and water management, and project financing decisions.

    Lingong’s growing mining fleet: BEV truck options and planning notes for engineers

    Lingong Machinery Group is expanding its new energy mining fleet with hybrid and battery-electric haul trucks and excavators from Jinan-based LGMG, complemented by electric-ready wheel loaders and dozing solutions from SDLG in Linyi. The group is targeting both surface mining and large quarry operations, positioning its battery-electric trucks for short-haul, high-gradient pits where regenerative braking can materially cut diesel use. For mine planners and fleet engineers, the move signals more competition to established OEMs in BEV truck classes and potential leverage in negotiating mixed diesel–electric fleets.

    Evolution Mining’s S&P sustainability score: tailings and water lessons for engineers

    Evolution Mining has again secured a top position in the S&P Global sustainability rankings, recording a score of 68 for the second consecutive year. The assessment benchmarks miners on detailed ESG metrics including tailings governance, water stewardship and decarbonisation pathways, placing Evolution among the higher-performing gold producers globally. For geotechnical and operations teams, the ranking signals continued scrutiny of tailings storage facility design, closure planning and site water balances against S&P’s quantitative risk and performance criteria.
