Coal mining
Coal mining - Extraction, Processing, Pollution: In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon …

The coal mining life cycle
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.

Coal Mining and Processing
Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. For more posts like these, be sure to visit ...

Coal formation
Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or …
