South African Coal Mining Techniques Methods, Impact & Future

41 Surface Mining Surface mining is the predominant method used to extract coal in South Africa It involves removing the overlying soil and rock to access the coal seams There are two main types of surface mining techniques employed: 411 Coal mining’s 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 Coal Minerals Council South Africa

South African coal mining today Mining for schools

In 2018, South Africa produced 2526 million tonnes (Mt) of coal Sales of coal were valued at R1394 billion The country’s coal mining industry employs over 86,900 people, who earn some R247 billion Some 70% of South Africa coal production (red) and exports (black) South Africa produces in excess of 255 million tonnes of coal (2011 estimate) and consumes almost threequarters 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 Coal in South Africa

Coal mining and environmental sustainability in South Africa: do

This study investigates the effects of coal mining on environmental sustainability in South Africa in relation to the moderating role of institutions To achieve the study’s objectives, the fully modified least square (FMOLS), dynamic least squares (DOLS), canonical cointegrating regression (CCR), BayerHanck cointegration and Toda Large scale mechanised mining methods we use include: longwall mining, where a long wall of coal is mined in a single slice, usually by a large machine sublevelcaving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravityDigging deeper: Mining methods explained Anglo American

Guide to groundwater monitoring for the coal industry SciELO

Coal is found in South Africa in 19 coalfields throughout the country The majority of the coal reserves are located in the provinces of KwaZuluNatal, Mpumalanga, Limpopo, and the Free State, with lesser reserves in Gauteng, North West and the Eastern Cape (Jeffery, 2005) Both underground and opencast mining takes place in South AfricaThis report highlights the coal mining methods, their significances, issues of concern and the stages of using coal after mining In 1977 the South African Department of Mineral and Energy(PDF) COAL MINING METHODS ResearchGate

Approximately only onequarter of South African coal reserves are economically and technically recoverable with current conventional mining methods (Barker, 1999) UCG deployment can create new highvalue jobs in the drilling, gas processing, and gas engine maintenance industriesThe 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 SOUTH AFRICAN COAL SECTOR REPORT Energy

Currently, South African coal mining operations emphasize an endofpipe treatment approach to coal waste and acid rock drainage (ARD) management Chemical techniques for ARD treatment, such as lime neutralization, typically consume large amounts of costly reagents, generate significant quantities of sludge, and are typically Key facts and figures The coal industry employed 90,977 people in 2022 2312 million tonnes produced in 2022 with total coal sales of R2523 billion 70% of coal volume is consumed domestically and more than 70% of Coal Minerals Council South Africa

Unconventional extraction methods to harness the energy and carbon in coal

In South Africa, coal accounts for about 75% of the country's primary energy supply As a nonrenewable resource, there is an increased need for sustaining the coal reserves Some South African coal resources are unminable due to various reasons, including being at too a great depth to be economically mined or of too low rank to beutilizedSouth Africa had 99Bnt of proven coal reserves as of January 2019 The country produced 2566Mt coal in 2018, of this 986% was thermal coal and remaining 14% was metallurgical Meanwhile, the country stood as the world’s sixth largest coal consumer, with demand mainly driven the domestic power industry, accounting for 668%South Africa Coal Mining to 2023 GlobalData

Some 47% of South Africa’s coal is produced from bordandpillar mining, stoping and longwall mining, types of underground extraction which access coal up to 300 metres under the ground Miners travel by lifts down a mine shaft to reach the depths of the mine or enter by means of decline shafts or adits for shallower minesThen, by comparison to the $85billion pledge to phase out coal as its main energy source, it will be imprudent to take a singleminded view to this proposal, considering South Africa is aThe future of coal in South Africa Mining Weekly

Journal of the Southern African Institute of Mining and Metallurgy

Introduction Longwall mining is currently the safest and most effective method for soft rock deposits, especially coal Unlike room and pillar, which has a typical extraction range of 4060% depending mainly on depth and seam height, longwall mining has typically around 80% extraction and is also used for deep coal deposits (>1000 m)
