Abstract
A mine roof support includes a substantially dome-shaped plate including a curved portion having a first side and a second side. The mine roof support includes a drive end such as a barrel and wedge assembly, a nut or a forged head. The first side of the plate is adapted to mate with a recess defined in a mine roof. A top portion of the drive head may be contoured to substantially match the contour of the second side of the plate. A drill bit tool used to create the recess includes a first drill bit situated at one end of the drill bit tool and a second drill bit situated near an opposite end of the drill bit tool, wherein the drill bit tool is adapted to drill a bore hole and the recess. A method for supporting the mine roof utilizes the mine roof support.
