摘要
The mine tunnel cladding mats consist of longitudinal wires (1 to 6) with other wires (7, 8 etc.) welded across them to form a grid, and attached to I-beams (33) parallel to the cross wires (7, 8 etc.). The cladding has the longitudinal wires divided up into sets of six, where the four middle wires (2 to 5) have an intermediate straight portion (2a - 5a) and ends (2b - 5b, 2c - 5c) which slope towards each other to meet at a point, where they hook round the beam (33) and are interlocked and secured by loops (35) under the beam. The two outer longitudinal wire (1, 6) slope very slightly at the ends (1b, 1c, 6b, 6c) and hook separately around the beams.
