Abstract
A conveyor gathering systems suitable for use with a continuous narrow seam mining machine is disclosed. The system is a single continuous conveyor extending from the auger or cutting head to the rear or discharge end of the machine and is particularly useful with a dozer gathering head. Conveying of the mined material is achieved by an endless conveyor comprised of "flight bars" attached at each end to two drive chains. The single continuous conveyor is driven from the rear of the mining machine, may pivot up and down, and makes a very small diameter, 180 degree turn around, at the front of the mining machine adjacent the auger or cutting head. Because the conveying system uses a single continuous system of flight bars, the tensions on the conveyor can be significantly reduced such that the conveyor drive motor can be selected having a work capacity less than one half of other systems.
