Steel Mine Arches

Introducing Steel Mining Arches, Abexsteels steel roof support systems which come in various sizes and combinations available as standard or produced as per drawing.

Can offer annual contracts at fixed pricing.

Produced within 10 days ex Europe to all international manufacturing standards.

Factory has more than 50 years’ experience, producing in excess of 15,000 tons annually.

Steel arches type THN Ω, as used in tunnels and roadways providing not only a higher resistance but also a higher yielding support.

The use of Ω steel arches in tunnels for underground mining support provides not only a higher resistance but also a higher yielding support.

A danger exists when the surrounding ground pressures increase, putting stress on the structure, but with this design, arch failure is reduced.

Some of the many advantages of our steel arches can be detailed as follows:

  • Much higher stress resistance – transversal and longitudinal
  • Higher section convergence
  • Easy and fast assembling
  • Improved sizing to the excavated section, resulting in a wider available area
  • Less ventilation required for air circulation, there is a lower resistance in the roadways
  • Can be re-used after recovery and cold forming
