Once a vein of ore is discovered, it is no small challenge to successfully remove it from the earth. Mining remains one of the most dangerous professions in the world. Poorly designed mines collapse, crushing those within. Unventilated mines fill with noxious gases, suffocating the victims before they are aware of their peril. Mines explode, or flood with water. Clearly, mining is no work for the amateur. The skilled Miner understands the system of braces, pumps and carts needed to allow access to the precious ore below and is able to keep a mine running while minimizing the peril to himself and his fellow workers.
