‌Mine Roadway Support System: Engineered for Underground Stability

Mine Roadway Support Steel Fabrication Engineered For Underground Stability‌

Safeguarding mining operations with robust steel arches designed for high-stress tunnels and dynamic geological conditions.

‌Core Specifications‌

  • ‌Material‌: High-yield steel (Q460C/EN S690QL) with yield strength ≥690 MPa
  • ‌Profile‌: Semi-circular or trapezoidal arches (4-8m span, 0.8-2.2m height)
  • ‌Load Capacity‌: Static 0.5 MPa / Dynamic 0.3 MPa (ISO 14688-2 compliant)

‌Critical Design Features‌

  • ‌Active Ground Control‌: Pre-tensioned cross-struts counteract rockbursts and convergence
  • ‌Modular Assembly‌: Bolt-connected segments enable rapid deployment in confined spaces
  • ‌Corrosion Defense‌: Hot-dip galvanizing (≥86μm) + coal tar epoxy coating for acidic environments
  • ‌Deformation Monitoring‌: RFID tags embedded for real-time stress monitoring via 5G mesh networks

‌Geotechnical Adaptability‌

  • Coal seams with gas outburst risks (ATEX Zone 1 certified)
  • Soft rock tunnels with >15% creep deformation
  • Deep mines (>1000m) under high geothermal stress

‌Compliance & Certification‌

  • MSHA 30 CFR Part 75 roof control standards
  • ISO 14689-1 geotechnical investigation alignment
  • EN 1090-2 execution class EXC4 for critical structures

Where geology challenges productivity, our steel arches deliver resilience.
