ABSTRACT:
A mine roof support for an underground mine gallery comprises a sole plate adapted to rest on the floor of the mine gallery. The sole plate is connected by links to the region of the lower end of a rear shield, and the upper end of the latter is connected by pivot means to a roof shield, between opposite ends of the latter, in such a manner that a portion of the roof shield between the front end thereof and the pivoted means is considerably longer than the portion of the roof shield between the pivot means and the rear end of the roof shield. At least one extensible and collapsible prop extends between the sole plate and the portion of the roof shield which is located forwardly of the pivot means and at least one additional prop extends between the sole plate and the rear shield, so that the roof shield may be pressed against the roof of the mine gallery and be shifted relative to the mine face.
