The most economical method of coal extraction from coal seams depends on the depth and quality of the seams, as well as the geology and environmental factors. Surface (opencast) mining and deep underground mining are the two basic methods of mining used in South Africa. Approximately 51% of South African coal mining is done underground and ...
the history of coal mining in south Africa Coal was discovered in KwaZulu-Natal, Mpumalanga and the Eastern Province, and first documented between 1838 and 1859. The first commercial mining took place near Molteno, in the Eastern Cape, in 18701. The discovery of diamonds at Kimberley in 1870 and gold on the Witwatersrand

mining and its development correlate closely with cultural progress. Mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials. One of such methods is the Bord and Pillar method of mining. Bord and Pillar method of mining is one of the oldest methods of mining.
Mining the Coal Coal miners use giant machines to remove coal from the ground. They use two methods surface or underground mining. Many U.S. coal beds are very near the grounds surface, and about two-thirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves.
similarities between the South African and Indian coal mining sectors. The comparison was based mainly on coal geology, mining methods used, and labour productivity. Table I shows the relative contributions of room-and-pillar and longwall mining to underground coal extraction in seven coal-producing countries.
Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside. Augering can be regarded as a supplementary method for open cast mining in

Coal Mining in South Africa Coal minings advent in South Africa can best be traced to the start of gold mining in the late 19 th century, particularly on the Witwatersrand, with the first coal in appreciable tonnages being extracted on the Highveld coal field close to the nascent Witwatersrand gold mines.
Coal miners who work and travel under supported roof expect to be protected from rock falls. However, rock fall accidents and injuries continue to occur in coal mines that have been supported according to the roof control plan. Experience at coal mines with large numbers of
Conventional mining is the oldest method. In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars. Continuous mining is the most prevalent form of underground mining. In continuous mining, a machine known as a continuous miner cuts the coal from the mining face, obviating the need for drilling and blasting.
Open-pit mining. Some 53% of South Africas coal is produced from surface mining, via open-cast or open-pit mines. This is because the coal is less than 60 metres below the surface. Open-pit mines use draglines, as well as truck and shovel operations to extract coal. A dragline excavator uses a dragline to pull a bucket by a wire cable.
