Patent ID: 8459750

Claim:
An assembly, the assembly comprising: a launching unit for highwall mining; an anchoring device for fixation of the launching unit; and a coupler for coupling the anchoring device to the launching unit; the anchoring device comprising: a hollow cylindrical body to be axially driven into a surface, wherein a distal end of the cylindrical body is provided with a cutting edge and the cylindrical body is configured to retain surface material within the hollow body in a driven position; a linear motion system for connecting the hollow cylindrical body to the launching unit to provide for absorption of horizontal and vertical vibrations and shock loads from the launching unit while providing for raising and lowering of the hollow cylindrical body relative to the launching unit for highwall mining; and a guide for guiding axial displacement of the hollow cylindrical body while allowing for axial and rotational movement of the cylindrical body during driving of the hollow cylindrical body into the surface.
