Abstract (en)
The invention relates to a steel wire mesh for supporting walls of mines and other subterranean constructions. The mesh comprises a number of parallel first mesh wires (1, 1'), which are arranged at a first distance from each other, as well as a number of parallel second mesh wires (2, 2'), which are arranged at a second distance from each other, perpendicular to the first mesh wires. The first and second mesh wires are attached to each other at the intersections of the mesh wires, preferably by welding. Furthermore the steel wire mesh comprises third mesh wires (3, 3') which are parallel to the first mesh wires, wherein an individual third mesh wire is arranged at a distance of 2 - 20 mm from the first mesh wire. The number of third mesh wires is smaller than the number of first mesh wires.
