ABSTRACT:
A mining machine includes a frame with a material dislodging head mounted on the end of the frame. Ground engaging tracks propel the machine within a mine along the floor of the mine to advance the dislodging head into the face of the mine to dislodge material therefrom. Roof bolting apparatus is employed for installing roof bolts at predetermined locations in the roof of the mine above the mining machine. The roof bolting apparatus is supported by a drill pit which is positioned within the frame and movable relative to the frame. The roof bolting apparatus is arranged to install roof bolts at predetermined locations above the mining machine while the mining machine is being propelled through the mine to dislodge material from the mine face.
