Yielding & Rigid Mine Arches
TH steel profiles are used in tunnels and roadways and provide a yielding, high resistance support as well as:
- High carrying capacity
- Higher resistance against all kinds of stresses
- Easy and fast assembly
- Custom design to fit the excavated tunnel thereby maximising available space
- Long working life.
As underground mines get ever deeper in search of supplementary orebodies, bearing forces become a significant issue in tunnel stabilization. Existing tunnel support methods become less effective at greater depth, and the need for additional reinforcement increases.
With some of the deepest mines reaching four kilometres underground, global trends suggest.
Incidents of rock bursts and tunnel failure are on the rise. The deeper the mine, the higher the stress level exerted on the surrounding rock. Heavier section profiles and optimising excavation shapes to endure higher stresses are developed for extremely difficult underground conditions.
