ABSTRACT:
In shoring a mine tunnel, use is made of a plurality of panels 11 each comprising a rectangular member with detents 15 formed in two opposed edges. The panel 11 may be composed entirely of sheet metal or may comprise spaced-apart rectangular or strips of sheet metal, with spaces between occupied by wire or rod mesh. The detents may comprise U-shaped tongues 18 defined by a C-shaped slot 16 and a T-shaped slot 17 the tongues acting in a hook like manner to interconnect the detents 15 on the superimposed edges of adjacent panels 11. Where the panel 11 is entirely of sheet metal, apertures 25 may be provided along the other pair of opposed sides for engagement of links such as 58; where the panel is partly of mesh such links can be looped through the mesh.
