ABSTRACT:
An improved bearing plate is used to support a portion of a mine roof. The bearing plate is stamped from sheet metal and has elongated ribs which define grooves facing toward a back side of the bearing plate. Reinforcing members are disposed in the grooves and are fixedly connected to the bearing plate. The reinforcing members increase the resistance of the bearing plate to deflection under the influence of loads applied to the bearing plate by the mine roof.
