A series of individual conveyor assemblies each having an independent endless belt conveyor extending longitudinally thereon are positioned in overlapping relationship. Each conveyor assembly includes a pivotal section adjacent a material receiving end portion thereof and is pinned to a material discharge end portion of a preceding section. The material discharge end portion overlies the material receiving end portion. The pivotal section connecting adjacent conveyors maintains the end portions thereof in material conveying relation as the assemblies extend along a curved path through the mine. A support beam is secured to the mine roof above the connected conveyor assemblies. Each conveyor assembly adjacent the receiving end portions thereof is secured to the support beam by a roller assembly that is longitudinally movable on guide tracks of the support beam. The conveyor assemblies are arranged to move on the support beam in response to the movement of a continuous mining machine and convey the mined material from the continuous mining maching at the rate the machine dislodges the material from the mine face.

Cascading conveyor system

In an auger mining system which forms an opening in the earth comprising a pair of axially aligned cylindrical holes and wherein the opening has a bottom, the system has a pair of side-by-side conveyors. Each auger conveyor has a shaft and a flight around the shaft which shafts are journaled through bearings at each end to a spacing member and where the spacing members are rigidly tied to each other by a longitudinal member having an underside. A supporting apparatus including a skid is attached to the auger pair and extending to the bottom of the opening. The skid may be attached either to the underside of the longitudinal member or to each of the bearings. If the skids are attached to the bearings, then skids which are on adjacent bearings of mating auger pairs are arcuately staggered to permit side-by-side positioning of the skids.

Support system for a unitized pair of auger conveyors

A pair of side-by-side augers, each having a shaft, a mateable rotational coupling on each end of the shaft, and flights along the shaft, are unitized by journaling bearings on each end of the shaft with spacers pivotally attached between each of the bearings on the same end of the shaft in order to align the axis of the shafts substantially parallel with each other. A longitudinal support member is rigidly secured between the spacers and between each of the flightings. A communications channel is provided in such a unitized auger assembly by mounting a channel along the top of the longitudinal support member. Apparatus is provided for inserting and removing the cable from the channel.

Wire communications channel for a pair of unitized augers

Apparatus for unitizing a pair of side-by-side augers when each auger includes a shaft, a mateable rotational coupling on each end of the shaft, and flightings along the shaft, the unitizing apparatus includes bearings which are journaled on each end of the shaft and spacers pivotally attached between each of the bearings on the same end of the shaft in order to align the axis of the shafts substantially parallel with each other. A longitudinal support member is rigidly secured beween the spacers and between each of the flightings. A joining clevis is attached to the spacers so that they face in a manner to mate for interconnection with subsequent or preceding unitized assemblies.
