Machinery used in the mines.
When a man checked in for his shift, he took his brass medallion into the mine with him. In the event of an accident, the rescue crew could tell who was still in the mine.
In the early days, miners used a small sledgehammer and drill to make holes for blasting.
After the dynamite pulverized the rock, a mucker would shovel it up and haul it away for processing.
Shortly after 1900 powerful pneumatic drills reduced fatigue and improved output.
This is a sample of the amazingly beautiful ore they were mining. Azurite and Malachite on Goethite or copper carbonate hydroxides on iron oxide hydroxide.

Into the Copper Queen Mine.
Shift boss's office
This very large cavern was created when high grade copper ore, 23% copper, was removed. Our guide told us that the miner drilling in the upper right opening has not moved in years.
Ore from upper levels was dropped through shafts to a lower level. A miner opened the gate and the ore cart was filled with 3/4 ton of ore. He then pushed it to the mine entrance, dumped it and returned for another load. His shift was 10 hours. Later the men were replaced by mules who could pull 4 ore carts at a time.
