2. Mining Methods - Copper
Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the underground mine develops. In both mining techniques, the mined ore must be removed from the mine and transported to ...
