Abstract: A mining system and components for conveyance of mined material. The system may include a continuous miner, a series of one or more conveyor carts, and a loader, coupled in series. The loader may include a first end to be connected to the second end of the series of carts, a feeder assembly proximate to the first end of the loader and also having a first end and a second end, and an elevator at the second end of the feeder assembly. The feeder assembly may include a plurality of spaced paddles connected to endless chains. The paddles convey mined material through a bin and to the elevator. Carts may be stackable, with leg supports of an upper cart being received on the side rails of an adjacent lower cart. Couplings include male and female connectors that couple when advanced toward each other.
