ABSTRACT:
A drill boom is connected at its rear end portion to a mobile body and supports at its front end portion a drill pot for rotating a drill steel. The drill boom raises the drill pot along a predetermined straight-line path to advance the rotating drill steel into the mine roof to form a bore hole for insertion of a roof bolt assembly. An operator's compartment is slidably mounted on the front end of the mobile body laterally of the drill boom. A hydraulic cylinder positioned on the mobile body raises the operator's compartment along a plane aligned with the plane of movement of the drill pot. A protective canopy overlies and is movable with the operator's compartment. A drill steel guide is secured to the canopy and includes movable guide portions that extend into surrounding relation with the drill steel. The drill steel guide is elevated with the canopy to a position adjacent the mine roof. The guide maintains the drill steel along the predetermined straight-line path as drill steel advances into the mine roof by upward movement of the drill boom.
