Economic activity in modernday South Africa has been centred on mining activities, their ancillary services and supplies. The country''s stock exchange in Johannesburg was established in 1887, a decade after the first diamonds were discovered on the banks of the Orange River, and almost simultaneously with the gold rush on the worldfamous Witwatersrand.
Mining in South Africa has always required extremely high levels of skill in numerous different fields, ranging from metallurgy to shaft sinking, from ventilation to chemistry, from work that can be done by men and women in laboratories wearing white coats to more perilous work by men and women in overalls deep underground.

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, which accounts for just under half of total coal production (SACRM, 2011). This method is ideal for relatively shallow deposits where overlying rock pressure is low.
Barrick Gold Corporation has one of the largest openpit 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 world''s deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground.
These are all extracted during the mining process. Because of the rarity of pgm and its tendency to combine with other metals, the mining process often yields far more nickel or copper than it does platinum. In South Africa, the world''s largest producer, platinum is mined in an area called the Bushveld Igneous Complex.
The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

Gold mining in South Africa. Across the globe, where new discoveries of gold are becoming increasingly rare and in inhospitable locations, South Africa''s goldfields still offer excellent opportunities for gold miners, with estimated reserves of 6 000 tons. Gold mining in South Africa accounts for around 10% of global gold production.
If minerals are found deeper, as is the case with most of the gold in South Africa, underground mining is used. Underground mining (shaft mining) South Africa''s thin but extensive gold reefs slope at an angle underneath the ground, and this means that some .
