The global ground support and rock bolting market enters 2026 on a structural growth path: the rock bolts segment is projected to grow from about USD 817 million in 2024 to USD 1.18 billion by 2032 (5.7% CAGR), with underground mining accounting for roughly 55% of demand, and industry forecasts pointing to a 4.2% CAGR through 2035 as mines go deeper and safety regulations tighten. The single most relevant signal for friction bolt suppliers: proceedings from the 2025 AusIMM Underground Operators Conference project a 35% rise in 2026 demand for immediate-acting ground support solutions such as friction (split set) bolts, driven by real-time stability risks in blocky and squeezing ground. Corrosion-related component failure now accounts for an estimated 40% of underground roadway reinforcement issues, pushing demand toward galvanized systems. For buyers and engineers specifying friction bolts and split sets, the 2026 picture is clear: deeper mines, higher support density per ton, and a premium on immediate, mechanization-compatible, corrosion-resistant support.

1. Mines are going deeper — and support density is rising. As surface deposits deplete, mining companies are extending operations to greater depths where rock stress and instability increase, requiring more intensive ground support per ton of extracted material. Copper and gold mining are seeing increased investment as electrification and the energy transition drive metal demand — with new underground developments in Chile, Peru, Australia, and Canada — while coal remains robust in China, India, and Indonesia.
2. Immediate-acting support is the fastest-moving requirement. The 2025 AusIMM Underground Operators Conference — attended by more than 1,500 mining professionals — highlighted inconsistent component quality and protocol deviations as top contributors to ground support incidents, and projected a 35% rise in 2026 demand for immediate-acting solutions such as friction anchor bolts. Split sets deliver full-length frictional support the moment they are driven, which is exactly what fast-advancing headings, blocky or squeezing ground, and first-pass seismic support require.
3. Corrosion is the hidden failure driver. Data from the AWS Musselwhite Mine technical report links corrosion-related component failure to roughly 40% of underground roadway reinforcement issues, driving demand for galvanized and corrosion-resistant systems — and creating a premium segment for coated bolts, plates, and accessories.
4. Mechanization and automation are changing specification. Maptek video analyses and industry trends show a shift toward mechanized installation compatibility to reduce human error. Automated drilling and bolting (ADB) systems are moving from pilot stages to broader deployment in large metal mines, favoring engineered components with consistent geometry — including precision-formed split sets, plates, and accessories that install reliably under jumbo and bolter rigs.
5. Safety regulation is codifying quality. Stringent mine safety regulations worldwide mandate certified ground support systems, raising compliance costs but also driving adoption of higher-quality, traceable products. The global mining industry now spends more than USD 4 billion annually on ground support, with rock bolts accounting for about 35%.
Premium moves to corrosion resistance. Galvanized friction bolts, dome plates, and accessories are the growth sub-segment as corrosion-related failures reshape material specifications.
Immediate support is being specified first. Split sets and friction stabilizers are increasingly the first-pass support of choice in seismic and squeezing conditions, with resin and cable bolts reserved for permanent reinforcement — see our split set vs resin bolt vs cable bolt guide for the decision framework.
Diameters and lengths are standardizing around deep-mining loads. The FB-47 heavy-duty class is the reference for deep mines and high-stress headings where smaller bolts cannot deliver sufficient anchorage; our FB-47 technical guide covers its specification in detail.
Verification is part of procurement. Pull testing, inspection, and certified manufacturing documentation are becoming standard requirements — bolt pull testing and quality control capabilities now differentiate suppliers in tender evaluations.
Specify immediate support for active ground. With the projected 35% rise in friction bolt demand, fast-advancing headings and squeezing ground should be supported with split sets as first-pass, full-length friction support — sized by diameter (33, 39, 42, or 47 mm) and length to match hole plan and failure zone.
Upgrade to corrosion-resistant systems. With ~40% of roadway reinforcement issues linked to corrosion, galvanized bolts, plates, and accessories are a direct reliability upgrade with lifecycle-cost justification.
Buy mechanization-compatible. Consistent geometry and tolerances matter for jumbo and automated bolter installation — verify the manufacturer's forming and quality control before ordering in bulk.
Demand verification data. Pull-test results, material certification, and inspection reports should accompany every batch — see our installation guide and inspection guide for the practical checklists.
