Abstract

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.
