In South Africa, mining for gold typically involves methods like panning, sluicing, dredging, hard rock mining and by-product mining. The most effective method used is hard rock mining, since reserves are typically encased in deep underground rock.
Long-hole stoping is the primary method of excavating the reef at South Deep. This is an efficient method to extract the large volumes required to mine the thick Elsburg reef package. The method can be described as a fan drilled radially from the stope access drives, with hole lengths designed so that the resulting area for excavation takes on the shape of a block.

The Hartebeestfontein Gold Mine is near Klerksdorp, South Africa. The site was first discovered in 1942. The Hartebeestfontein Gold Mine is a underground mining operation. Initial production took place in 1955 and overall output was considered to be large size. Mine operations consist of 2 distinct underground workings. There are a total of 8 ...
Kloof is a deep level underground gold mine located along the northern and southwestern margins of the Witwatersrand Basin in South Africa. This mine is typical of the many Witwatersrand Basin operations, which have been the primary contributors to South Africas production of a significant portion of the worlds recorded gold output since 1886.

It is a caving method particularly well adapted to relatively flat-lying, thin, planar ...
Aug 21, 2019 South Africas mining industry is a shadow of its former self, having contributed 21% to South Africas GDP during the 1980s, while in 2018, contributed a mere 7.3% towards GDP. The cost of unlocking the countrys significant gold reserves has also skyrocketed, having recorded some of the highest total US dollar per ounce cash operating ...

Witwatersrand in South Africa, also known as the Rand, is the most pro- ductive gold-mining district in the world. Surface gold was discovered in the region in 1884, and active mining operations began in 1886, the same year in which Johan- Figura 48 nesburg was founded as a gold-mining settlement.
Oct 29, 2021 South Africas gold mines, some of which are the deepest in the world, accounted for the highest number of fatalities during the period, followed by platinum mines, the council said. The mining industry employs more than 450 000 people.

Jan 21, 2020 South Africas reef deposits, especially gold and platinum-bearing ore bodies, are narrow and tabular. While legislation dictates a minimum operation height of 800 mm in areas where people work, some of the countrys narrow reef mines have ore bodies with thicknesses of less than 500 mm, which results in ore dilution, as waste ore with zero economic value is also mined.

The current turbulence in the mining industry in South Africa has its roots in several different factors. First, the fall in global demand for platinum and other minerals due to recession second, the consequences of the Marikana disaster in destabilising labour relations and third, the structural character of our mining industry. A great deal has been written about the first two factors, so ...
