The two copper disks are I.D. tags issued to the miners and are numbered. When a miner fills a coal car he hangs his I.D. on the side of the car. When the coal is dumped the miner gets credit for the weight of coal.
continuous mining machines (similar to those used in room-and-pillar mines) to block out panels of coal.
