KNOTTED MESH AS SUPPORTING MATERIAL IN MINES

摘要

A method for lining mining and tunnel constructions with a support material (20) comprises the steps of:•a. providing a plurality of lay wires (24) in the long direction;•b. providing a plurality of stay wires (22) in the cross direction, the stay wires making intersections with said lay wires (24);•c. providing knot wires (28) to attach the lay wires (24) to the stay wires (22) in at least some of the intersections so as to form the support material;•d. installing the support material (20) against a ceiling or a wall of a mining or tunnel construction by means of bolts.
