An extensible conveyor apparatus and method for a continuous haulage system include a continuous conveyor belt for carrying coal or ore discharged from a continuous miner, a top slider for supporting the coal-carrying or ore-carrying continuous conveyor belt, a bottom belt return, and a slider holding frame for holding the top slider, wherein the slider holding frame is provided by a plurality of floor-supported frame members held in position by belt tension, the slider holding frame being 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 slider for supporting the mined-material-carrying belt is composed of a material which is lightweight, flame-resistant, and quickly replaceable in an underground mine.
