Coal mining - Coal mining - Underground mining In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of
Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in northeastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the worlds deepest hard rock gold mine up to 3,900 metres 12,800 ft underground.

Underground mining. Some 47 of South Africas coal is produced from bord-and-pillar mining, stoping and longwall mining, types of underground extraction which access coal up to 300 metres under the ground. Miners travel by lifts down a mine shaft to reach the depths of the mine or enter by means of decline shafts or adits for shallower mines.

There are three different mining methods that are commonly used in underground mines in South Africa. The most common technique is the bord and pillar method. This method is ideal for relatively shallow deposits
