SOUTH AFRICAN COAL SECTOR REPORT - Energy

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,Coal in South Africa - Wikipedia,South Africa produces in excess of 255 million tonnes of coal (2011 estimate) and consumes almost three quarters of that domestically. As of 2018, South Africa was the seventh largest producer and consumer of coal in the world. This large industry, means that as of 2015 about 80,000 workers, or .5% of total employment, was from the coal industry, down from a peak in 1981 of 135,000 workers. Around 77% of South Africa's energy needs are directly derived from coal. South Africa is the 5th large…The coal mining life cycle - Mining for schools,Open-pit mining. Some 53% of South Africa’s 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.

SOUTH AFRICA’S COAL INDUSTRY OVERVIEW, 2014

3. MINING METHODS Both opencast and underground mining methods are employed in South Africa for extraction of coal reserves. 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 depositsMining industry of South Africa - Wikipedia,Mining in South Africa was once the main driving force behind the history and development of Africa's most advanced and richest economy. Large-scale and profitable mining started with the discovery of a diamond on the banks of the Orange River in 1867 by Erasmus Jacobs and the subsequent discovery and exploitation of the Kimberley pipes a few years later.
