Abstract: A friction stabilizer having tabs comprising a tubular body comprising an exterior surface and having a first portion and having a second portion provided with a taper. The first portion has an impact end and the second portion has an insertion end. A tab is on the tubular body and extends outward from the exterior surface of the tubular body in a direction toward the impact end and away from the insertion end of the tubular body. The tabs can be rectangular shaped or triangular shaped or have other shapes which prevent the friction stabilizer from being removed from a drilled bore in a mine. When the friction stabilizer with tabs is inserted into a drilled bore in a mine, the tabs do not impede insertion. But, after insertion into the drilled bore the tabs resist removal of the tubular body, and thus allow the stabilizer to support the mine wall or ceiling. The friction stabilizer is made by taking a steel coil and punching the shape of the tabs in the metal, for example sheet metal, unrolled from the coil.

Abstract: A bearing plate for use in a mine comprising a first side, an opposed second and having an opening that extends from the first side to the opposed second side. The opening is defined by a surrounding edge wall formed in the bearing plate, and a tab extends from the surrounding edge wall into the opening. The tab is for being received in a longitudinal gap or slot of a friction stabilizer or a longitudinal slot or gap of an embossed friction stabilizer, and the tab prevents them from collapsing when they are subjected to loading.
