Abstract (en)
[origin: WO2013127617A2] A method for lining a support material in mining and tunnel constructions comprises the steps of: providing a plurality of lay wires in the long direction; providing a plurality of stay wires in the cross direction, the stay wires making intersections with said lay wires; providing knot wires to attach the lay wires to the stay wires in at least some of the intersections so as to form the support material; installing the support material against a ceiling or a wall of a mining or tunnel construction by means of bolts.
