Underground mining (hard rock) - Wikipedia

The mining method selected is determined by the size, shape, orientation and type of orebody to be mined. The orebody can be narrow vein such as a gold mine in the Witwatersrand, the orebody can be massive similar to the Olympic Dam mine, South Australia, or Cadia-Ridgeway Mine, New South Wales.The width or size of the orebody is determined by the grade as well as the distribution of the ore.
