    Abstract: A mine scaling tool having a base plate to which a collar is concentrically attached on one side and appropriately supported with gusseted rib plates. A relatively long, heavy walled tube is telescopically fitted within a reenforcing collar. The tube is cut at an oblique angle of approximately 15 degrees off vertical in the frontal plane at the end opposite the collar. A face plate is centrally positioned over the open end of the tube and adequately reenforced with gusseted rib plates and reenforcing bars. Picks are attached parallel to the face plate along all sides extending outwardly from the edges, thereby serving as tines.
