ABSTRACT:
Conveyor belt supporting modules associated with an endless conveyor belt assembly for conveying mined material from a mine bore to the mouth of the bore allows for necessary length of conveyor belt to be fed into the mine, and convey material from the mine, as the bore lengthens so that the conveyor belt always extends from adjacent the cutting site to the bore mouth. Each module has a carriage frame with a number of conveyor belt supporting return rollers extending between the frame sides, and a number of conveyor belt supporting trough roller sets mounted above the return rollers and spaced from each other from the front to the rear along the frame. The carriages have axles and wheels to allow movement into a bore, and they are connected together by couplers. The supporting trough roller sets are mounted for pivotal movement on a frame side to expose the return rollers so that the endless belt can be laid in place simply and quickly. An assembly, including a supporting structure, mounts a belt take-up unit and a number of modules are stacked one above the other on the right and left sides of the take-up unit, and are moved, in sequence, into operative association with the take-up unit to be fed into the bore mouth. The supporting trough roller sets on the left side of the take-up unit pivot about the left sides of the frames thereof, while those on the right side pivot about the right sides of the frames.
