ABSTRACT:
Conveyor apparatus and method are disclosed for continuous haulage of coal or ore in an underground mine, including a plurality of floor-supported frame members held in position by belt tension and further held in position optionally by bolts or pins. The novel holding frame provides rapid and efficient extendable, retractable construction in the mine. The novel continuous haulage system handles larger and heavier pieces of equipment and can be pulled to a different position in an underground mine as a complete unit.
