SOUTH AFRICAN COAL SECTOR REPORT Energy
2018-5-25 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

2017-7-11 Coal seams are relatively thick and close to the surface, which allows for low-cost mining; a quarter of South Africa’s bituminous coal is between 15-50 m below the surface and much of the remainder between 50-200m. Half of reserves are in seams 4-6m thick and a further third in 2-4m seams (Petrick Commission, 1975).

An assessment of South Africa's coal mining sector
South Africa depends on coal-derived energy, electricity in particular and the coal mines are implicitly exposed and vulnerable to the adverse impacts of climate change. Reducing this exposure and vulnerability dictates the urgent need to implement anticipatory adaptation measures in all the sub-chains of the coal mining value chain.
