Application
High-strength prestressed strand and precision rolled threaded bar engineered for underground roadway support, slope stabilization, and anchor systems — built to hold ground under conditions ordinary construction-grade steel isn't designed for.
Underground roadway support and open-pit slope stabilization put steel under a very different kind of stress than surface construction: rock convergence, blast vibration, and long-term ground movement can bend, stretch, or shear an anchor bolt well before it ever reaches its rated tensile load. A rock bolt or cable bolt that lacks sufficient ductility can snap under sudden rock movement instead of yielding safely — and once installed underground, replacing a failed anchor is far more disruptive and costly than in any above-ground application.
For mining engineers and geotechnical contractors, the real sourcing question isn't just tensile strength on paper — it's whether the bolt or cable strand can absorb dynamic rock loading without brittle failure, hold anchorage in humid or acidic mine water conditions, and meet the specific coal or mining industry standard required for underground use.
Yuanxian supplies mining-grade Prestressed Steel Strand for underground cable bolting — long anchor cables grouted into boreholes to reinforce roadway roofs and ribs against rock convergence. Its high tensile strength combined with adequate ductility allows the cable to absorb ground movement rather than failing abruptly, which is critical in active mining areas subject to blasting and stress redistribution.
For shorter-span roof and rib support, and for slope anchor systems in open-pit operations, our Precision Rolled Threaded Steel serves as full-column resin or cement-grouted rock bolt bar. Its continuous thread profile allows the bolt to be coupled to extend length on site and torqued to a bearing plate for immediate roof support, then supplemented with grouted anchorage for long-term stability.
*Elongation and anchor load figures are typical reference values for mining-grade bolt and cable strand; actual figures depend on bolt diameter, grade, and grouting method — confirm with our technical team for your ground support design.
| Requirement | Yuanxian Mining-Grade Strand / Bar | Generic Construction Rebar |
|---|---|---|
| Ductility under dynamic rock convergence | Verified elongation, yields before snapping | Lower ductility, higher brittle-failure risk |
| Full-length coupling for on-site bolt extension | Continuous thread profile | Requires welding or mechanical splices |
| Corrosion resistance in humid / acidic mine water | Galvanized & epoxy-coated options available | Limited or unavailable |
| Compliance with mining industry standards | GB/T5224, MT/T series, GB50086 | Typically general construction standard only |
Our mining-grade prestressed strand and threaded rock bolt bar are manufactured in accordance with recognized national and industry-specific standards, selected according to underground or surface application and destination market:
We support mill test certificates and documentation required for mine safety authority review and procurement tender processes.
