Abstract (en)
A mining machine roof bolting rig (118) in which a drill or bolt head (408) is mountable at a main frame (101) of a mining machine via a first and second rig base frame (300, 301). A link arm (403) extends between the second base frame (301) and a carrier support (404) that mounts the drill or bolt head (408) via a conventional carrier arrangement. Pivot mountings between the first and second frames and the link arms (403) allow both forward and rearward and lateral sideways movement of the drill or bolt head (408) to achieve a plurality of different bolting or drilling positions above the mining machine (100).
