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.
Claims10
A tractor mounted, mine scaling tool comprising:
- a) a base plate;
- b) a tubular column attached perpendicular to said base plate;
- c) a face plate attached perpendicular to said tubular column opposite said base plate;
- and
- d) a plurality of picks attached parallel to said face plate, extending outwardly beyond said face plate.
A tractor mounted, mine scaling tool comprising:
- a) a base plate;
- b) a reenforced tubular column, attached perpendicular to said base plate, vertically supported by rib gussets;
- c) a reenforced face plate, symmetrically orientated with said base plate, attached obliquely to said tubular column, opposite said base plate;
- and
- d) a plurality of picks attached parallel to said face plate, extending outwardly beyond said face plate.
A method of mine scaling comprising the steps of:
- a) mounting a rigid tool having tines extending therefrom to a tractor loader;
- b) positioning said rigid tool in contact with a mine's roof or wall;
- c) driving said tractor loader forwards and backwards while maintaining contact with said roof or wall;
- d) dislodging loose material from said roof or walls of said mine;
- and
- e) repeating steps a-d until all loose material is dislodged.
