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.
Abstract: Apparatus for the handling of dislodged particulate material within a mine includes a base member having ground traction means with a body member supported on the base member. Vertical side plates on opposed sides of the body member secured thereto define a longitudinal material receiving bin. An endless main conveyor located within the material receiving bin has a receiving end and a discharge end. The receiving end when used as a surge hopper is adapted to continuously receive material dislodged from an adjacent continuous mining machine. A delivery conveyor receives material from the discharge end of the main conveyor and discharges it into other conveying means such as a shuttle car or an endless belt conveyor. A portion of the main conveyor positioned adjacent the discharge end thereof moves or pivots upwardly about a transverse horizontal axis and thereby assumes a position for maximum discharge of the material.
