The transportation of coal out of a mine is usually done by a serially linked system of conveyors. It is apparent that in a serially dependent system of this type the failure of any one component (conveyor) causes the complete system to be shut down. The provision of bunkers at strategically located points in the conveyor system can result in the production of coal even in the event of failure ...

Skips are shaft conveyors for hoisting ore/coal or waste from the underground. The most significant feature is the method by which ore/coal is discharg ed from the skip. Skips now in use are almost always the bottom-dump design. Skip loading is often automated in conjunction with automated slumping and automated ore/coal hoisting systems.

From the looks of it, the conveyor was at the back of the structure. There would be a siding along the back of the tower, and a pit between the rails. The pit was built with slanted walls that allowed the coal to drop into an area where the conveyor buckets would fill and be raised into the coaling tower.
