ABSTRACT:
A conveyor for use in mineral mining comprises a plurality of channel sections arranged end-to-end, and a guide disposed on one side of the channel sections for guiding a mining machine. The guide is constituted by a plurality of guide sections joined together by detachable connection means. Each guide section is attached to a respective channel section. The guide is provided with upper and lower channels separated by spacers, the channels receiving and guiding a chain for driving the mining machine. Each guide section is provided with a cover plate which is pivotally attached thereto for movement between a first position, in which it covers the guide channels, and a second position, in which the guide channels are accessible from said one side of the channel section. The detachable connection means associated with each adjacent pair of guide sections is constituted by recesses formed in adjacent spacers of that pair of guide sections, and a connector which mates with the recesses. The recesses are positioned to lie adjacent to the cover plates of that pair of guide sections when said cover plates are in that first position.
