THN ARCHES
THN Steel Arches for Underground Mining and Tunnelling
THN steel arches are structural support systems designed for underground excavations where additional steel reinforcement is required to control deformation and maintain excavation stability.
They can be used in mining galleries, tunnels and other underground structures where ground conditions require structural support in addition to conventional rock reinforcement.
Applications
- Underground mining
- Mining galleries
- Tunnelling
- Underground infrastructure
- Ground support
- Deformable ground
- Excavations requiring steel structural support
Steel arches can be combined with rock bolts, mesh, shotcrete and other ground support systems depending on project requirements.
