OSTI ID:7228446
Material is continuously dislodged by a pair of conical cutters and displaced outwardly toward the ribs of the room as the mining machine advances. The dislodged material is picked up by a transversely extending spiral conveyor and conveyed inwardly from the ribs onto the bottom strand of a flexible belt. The flexible belt has one end portion coiled on a lower rotatable spindle at a fixed discharge station adjacent the room entry. The other end portion of the flexible belt is coiled on an upper rotatable spindle positioned above the lower rotatable spindle. The intermediate portion of the flexible belt forms a lower conveying strand portion extending from the lower coil around a cylindrical idler or turn around pulley and an upper strand portion extending from the upper spindle to the turn around pulley. The upper strand portion extends between a pair of driven compression rollers to pull the upper strand toward the mining machine from the upper spindle. 11 claims, 6 drawing figures.
