ABSTRACT:
An extensible conveyor apparatus and method for a continuous haulage system and continuous conveyor belt are disclosed for carrying coal or ore discharged from a continuous miner. A top roller-slider combination supports the coal-carrying or ore-carrying continuous conveyor belt. A holding frame for the top roller-slider and a bottom belt return is provided by a plurality of floor-supported frame members held and secured in position by belt tension. The holding frame is capable of rapid and nimble extendable, retractable construction in the mine. Rails connect and hold adjacent frame members in position by press-fit attachment of the rails to the frame members. The rails preferably are quickly rotatable to change the top wearing surface. A top roller-slider for supporting the mined-material-carrying belt includes a combination of rollers and sliders composed of a material which is lightweight, flame-resistant, and formed into a roller slider combination insert which is quickly replaceable in an underground mine.
