Abstract

See full text

A drilling apparatus including a drill is disclosed for use with a mine roof bolter. The apparatus includes a support adapted to rotate the drill about two different axes. The first axis may be a vertical axis and the second axis may be a horizontal axis. The drilling apparatus includes a mast for supporting the drill and allowing relative movement of the drill with respect to the mast. The drilling apparatus additionally includes an element for longitudinally moving the mast with respect to the support. The drilling apparatus may further include a mesh aligner for aligning the mesh with respect to the drill. A drill guide with a small footprint may also be included which is capable retracting within a housing to avoid interference with a face of the mine when positioning the drilling apparatus.
