Geobrugg high-tensile steel meshes are used in mines for reinforcing existing infrastructure or ensuring the utmost stabilization for new structures from the onset, from box cut to abandonment of a tunnel. Together with the mechanized unrolling device MESHA® mounted onto standard drilling jumbos or bolters, the high-tensile MINAX® meshes can be installed in a single process. During installation, the crew is never exposed to working under unsupported ground.
