Lagging mat for mine supports

摘要

The invention relates to a freely forepoling so-called flat-hook mat in which, due to appropriate design of the locking members, early load-bearing capacity at high yielding capacity through change in shape is achieved by virtue of the fact that the bend of the other lagging mat, which bend is enclosed by the hairpin-like hook of the lagging mat, is extended essentially parallel to the extent of the longitudinal wire of the mat by a trough part and carries the transverse element at a distance from the bend.
