TECCO Mesh

详情

TECCO Mesh which has a tensile strength of 1,**0N/mm², pro-tects against rockfall, rock bursts and squeezing ground in underground mining and tunnelling. TECCO Mesh can carry higher static and dynamic loads than traditional reinforcement nets.

The wire is sufficiently tough and does not behave in a brittle manner. It can be stretched over sharp rock edges without sustaining damage. The mesh is diamond-shaped and along the edges, the wires are bent over and double twisted in such a way that this connection is as strong as the mesh it-self. The mesh is produced in rolls and can be manufactured in widths of up to 3.5m, in wire diameters of 4mm, 3mm or 2mm and in tailor-made lengths corresponding to the tunnel surface.

With the ROCK MESH installation handler, compatible with all multi-arm drilling jumbos, the TECCO mesh is unrolled onto the wall in roll widths up to 3.5m and bolted by the jumbo operator in the same working process, thereby providing a fast, safe and fully mechanized installation. The mesh rolls are mechanically picked up by the jumbo with the ROCK MESH, thus minimizing manual han-dling under unsupported sections of the drive.
