METHOD AND APPARATUS FOR TRANSFERRING MINED MATERIAL

摘要

A self-propelled body portion has spaced parallel vertical plate members that form a longitudinal passageway in which is positioned an endless conveyor. The conveyor includes a material receiving end portion that is maintained in underlapping relationship with the conveyor of a continuous mining machine that dislodges material from the face of the mine and deposits the material onto the receiving end portion of the conveyor. The conveyor transfers the mined material longitudinally of the body portion to a discharging end portion that pivots about a vertical axis relative to the main conveyor and discharges the mined material into a shuttle car. A pair of horizontally extensible drill booms are pivotally mounted to opposed sides of the body portion to swing laterally toward and away from the body portion. Each of the drill booms support at their end portions drill units that are vertically movable into position adjacent the mine roof for drilling bolt holes and installing roof bolts in accordance with a preselected pattern in the mine roof. Vertically and laterally extensible roof supports are mounted on the body portion and temporarily support the mine roof during the roof bolting and mining operations. Additional features include remote control of the continuous mining machine rearwardly thereof at a location beneath a supported section of the mine roof and remote control of adjustable roof support units that are mounted on the continuous mining machine.
