‌Mine Roadway Support System: 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.
