Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.

Mining: The process of taking out minerals buried under the rocks is called mining. There are two main methods of mining, viz. open-cast mining and shaft mining. Open Cast Mining: When minerals are taken out by removing the surface layer, the process is called open-cast mining. Minerals which lie at shallow depths are extracted by this process.
Uranium Mining Overview. (Updated December 2020) In the last 60 years uranium has become one of the world's most important energy minerals. It is mined and concentrated similarly to many other metals. While uranium is used almost entirely for making electricity, a small proportion is used for the important task of producing medical isotopes.
machineries, continuous mining system with improved design, development of modern generation, explosives and accessories, process innovations and application of information technologies and increased adoption of computerized mine planning and control.

The bauxite industry in Malaysia experienced a surge in January 2014, particularly in Kuantan, the state capital of Pahang. Bauxite is the ore that contains aluminum in its natural form, namely alumina (Al 2 O 3) at roughly 50% to 70% [].Bauxite is found 1 or 2 m below the soil surface and commonly mined with the strip mining (opencast mining) method by removing the overlying soil layer [].
Oct 26, 2018· Coal mining is a process that is carried out stepwise or in cyclic manner. The principle comprises rooms as a result of mining, and for stability purpose, pillars are left (Nayak and Dalai 2010). The process of mining is conducted in different rooms at the same time. After blasting, the coal is moved from rooms towards the conveyer by shuttle cars.
Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface ...
