ABSTRACT:
A conveyor cart for a mining machine is made from readily available components, including conventional golf cart components, and has a maximum height of 20 inches or less (e.g. about 18 inches) so that it can be effectively utilized with a continuous miner for mining ultra thin coal seams. A chassis has side rails with front and rear ends and cross pieces extending between the side rails. A first coupling mechanism, such as an eye bolt, is mounted adjacent the front end, and a second coupling mechanism, such as a pintle hook, mounted adjacent the rear end. A single axle containing a pair of inflatable golf cart wheels extends between the side rails and may be driven by a conventional golf cart transmission and an AC motor. An endless conveyor belt is mounted so that it has a top portion for conveying mined material from the continuous mining machine to the mine mouth, and a bottom portion beneath the top portion, the conveyor belt powered by an electric motor mounted to the chassis. The cart includes an electrical cord with female and male plugs at opposite ends, and can support a safety cable and an electrical cable that go from the mine mouth to the continuous miner.
