The complexity of the system is due to the joint venture between South 32 Limited and Anglo American Inyosi Coal. The conveyor system feeds coal from both mine sites to the Phola coal washing plant. The coal washing plant separates the coal into two products, i.e. coal for Eskom consumption and coal for export.

Coal Mining, British Coal and The Environment Flashcards
Opencast coal mining takes place from quarries or open pits at the surface. All the overburden is removed and the depth of this overburden is critical to the economics of the mine. The overburden is waste rock and piled up as a spoil heap. Blasting is then used to break the coal up and large machines called drag line excavators are used to

Open-pit mining
Open-pit mining, also known as mega-mining, open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow . This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.

Dragline Excavators and Mining
For large mining operations a bigger, heavier dragline excavator is needed. This type of equipment must be built onsite. It would cost too much to transport. These huge dragline excavators are meant to stay in place – and in service – for decades. Onsite dragline excavators are typically used in coal and oil sands strip mining.

Opencast Mining
Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use

Lesson 7.3: Mechanical Surface Mining Methods
Open cast mining is usually associated with coal or other tabular deposits that are more or less flat-lying. A significant difference between open pit and open cast mining methods is that in open cast mining, overburden that is removed to gain access to the ore is immediately placed in the previously mined cut.

Coal mining
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited.

The two mining methods used in coal extraction are surface “Open Pit” mining and Underground mining. Simply put, surface mining is peeling back the earth and collecting coal near the surface. Whereas, underground mining requires tunneling and building shafts. The mining method chosen by companies depends on the coal deposit being extracted.
