Dec 18, 2017· Similarly, a large coal mine in a "one mine town" is the monopsony buyer of miners in that region. Thus all the history of "company stores" and related abuses of miners. Oddly, the "fix" was to form labor unions for miners so that they had some local monopoly power to offset that monopsony abuse.
The miner had a conveyer belt system that dumps all the coal behind the miner. Then, a "scooper" comes and picks up the coal and takes it to a pit connected to another system of conveyer belts. Before the coal is sent out of the mine on the conveyer belts, it is broken down into smaller pieces by a rotating crusher.
