Abstract
A clamp for use in a mine stopping formed by a plurality of elongate extensible panels extending vertically from the floor to the roof of a passageway in a mine. The stopping comprises a series of main panels extending vertically side-by-side, with a space between two adjacent main panels, and a lap-over panel extending vertically and bridging the space. The clamp comprises a crosshead adapted to fit in the lap-over panel extending laterally of the lap-over panel and a hook-receiving stem slidable on the crosshead lengthwise of the crosshead. The slidable hook-receiving stem is formed to have hooks at the ends of a wire tie hooked thereto with the tie extending around a bar to draw the crosshead via the stem toward lips of the lap-over panel to clamp the latter in place.
