Located in the province of Limpopo, Grootegeluk is one of the biggest mines in South Africa, producing an estimated 22 million tons annually. The mine was acquired by the heavy minerals company Exxaro in 1980 and currently employs at least 3000 people. This mine produces three types of the commodity; cooking, thermal, and metallurgical coal.

Openpit mining, or opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Openpit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is

Advantages and disadvantages of open pit mining. Open pit mining is profitable when the deposit is not very deep or when the terrain is sandy or delicate, so that underground mining is not possible. Labor costs are lower, both in excavation and transportation, and allow the use of large machinery .

Mining operations at Elga openpit. The Elga openpit mining involves conventional drilling and blasting operations with the use of shovels and draglines for removing coal and waste. The mining fleet comprises excavators, bulldozers, motor graders, dump trucks, fuel servicing trucks, and timber trucks.

Open pit mining is also called strip mining because the extraction process destroys vegetation, reduces habitats and pollutes the environment. Mining proponents argue that the process is more efficient, cost effective and safer than shaft mining. Environmental regulations help mitigate damage.

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a ''pit'', and

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

West Cumbria Mining won planning permission from Cumbria County Council on 19 March, 2019, to open a mine in Whitehaven – but, unlike others on this list, this will be a deep mine. It wants to use the £165m Woodhouse Colliery site to extract one billion tonnes of coking coal – about million tonnes annually – from under the Irish Sea.

Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and openpit mining (see Fig. ).Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock.

Coal is mined either by surface methods (opencut or opencast 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 ( Figure 11 ).

Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining

Open pit mining also called open cut mining or open cast mining is a surface mining technique used to extract rocks and minerals. It requires largescale equipment, including shovels and drills. Motor graders also play a role, maintaining haulage roads so that both equipment and mined material can be transported to and from the mines.

Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
