Abstract: There is provided a mesh system (2) comprising a mesh sheet (4) and a reinforcing member in the form of a cable (6) coupled to one side of the sheet (4). The cable (6) is coupled to the mesh by wire ties (7). Two lengths (6a) and (6b) of the cable (6) may overlap or be disposed in a mutually adjacent manner. The lengths (6a) and (6b) may be coupled together by U-bolts or crimped bands (9), which may also engage the underlying sheet (4).

Abstract: A monitoring unit for installation on a cable bolt comprises a tube designed to fit within a cable bolt hole and having a collar at one end thereof, a cable bolt adapted to be grouted in the rock at the centre of the tube, a base plate placed tightly against the tube collar adjacent the rock face, a centralizer sleeve designed to fit over the cable bolt to keep the cable centralized within the base plate and tube, an elongated measuring plate having a centre hole for insertion of the cable bolt to fit tightly against the base plate and a groove cut at equal distances from each side of the centre hole for allowing the measuring plate to bend if the rock moves with respect to the cable bolt, and a cable clamp for fixing the measuring plate tight against the base plate.
