coal production and extraction process in south africa

With regard to proven coal reserves, South Africa ranked number seven in coal production (extraction) in 20094. Coal is one of the important export commodities because of its vast mineral resource base. The country's rich endowment of minerals has played a key role in the evolution of the South African economy. For more than a century,

SOUTH AFRICAN COAL SECTOR REPORT Energy

2018-5-25  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, which accounts for just under half of total coal production (SACRM, 2011). This method is ideal for relatively shallow deposits where overlying rock pressure is low. Seams are mined leaving in situ coal pillars, which are big enough to

Solvent Extraction of a South African Bituminous Coal

2019-11-4  A model biomass-derived phenolic mixture was investigated for its solvent ability for extraction of a South African bituminouscoal at temperatures of 300–360 °C. A previous study showed that phenol gave the highest extraction yield of 49.5 wt. % (daf) forbituminous coal at 360 °C, with an oil yield of 26.3 wt. % (daf). The phenolic products produced from sweet sorghum bagasseviaan alkaline liquefaction process were identified and reported earlier and a model biomass-derived phenolic mixture wasformulated, evaluated and results used in this study. The model mixture gave an extraction yield of 37.1 wt. % (daf) and oil yield of16.9 wt. % (daf) at 360 °C. This solvent mixture was found to be less effective for high extraction yields when compared to phenolat mild temperatures. This could be due to phenol being a better hydrogen carrier than the solvent mixture during the internalredistribution of hydrogen in the coal.

The coal mining life cycle Mining for schools

2021-6-30  Some 47% of South Africa’s coal is produced from bord-and-pillar 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 mines.

South Africa: The future of underground coal

2018-9-25  This proposed amendment intended to make it clear that the extraction of syngas utilising UCG technology constitutes a mining process as opposed to a production process (Oil & Gas). There has been stagnation in the legislative process and it is hoped that regulatory certainty would be provided to the place of UCG technology in extracting syngas from qualifying coal seams.
