different types of coal from open cast mining
Coal mining
Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called open cast) mine Additionally, coal seam thickness and geology are factors in the selection of a mining method The most economical method of coal extraction for surface mines is the electric shovel or drag line The most economical form of underground mining is the loOpenpit mining, also known as opencast or opencut mining and in larger contexts megamining, is a surface mining technique of extracting rock or minerals from the earth from an openair 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 Openpit mines are used when deposits of coOpenpit mining

The list of commodities is extensive, although the relative proportions mined underground and on the surface vary from mineral to mineral Massive tonnages of hard coal and lignite are also produced from surface mines, although the terminology used open cast or open cut, rather than openpit indicates that the technology and engineering concepts used Strip mining Strip Mining: Strip mining is a kind of surface mining The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it To mine the ore, these layers have to be removed The steps Types of Mining Definition, Examples, Diagrams Toppr

Open Cast Mining Open cast mining is usually associated with coal or other tabular deposits that are more or less flatlying 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 cutIt is significant to note that, among the various types of mining, openpit coal mining is one of the most destructive activities in terms of its impact on the surface landscape and the(PDF) AN OVERVIEW OF MINING METHODS ResearchGate

OpenPit Mining Definition Anglo American
Openpit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground Openpit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels This surface mining technique is used when mineral or ore deposits One that delivers coal into another conveyor or into a mine car Feeder A machine to feed coal onto a conveyor belt evenly Gathering Conveyor/ Gathering Belt A conveyor to gather coal from other conveyors, and to deliver it into mine cars, or onto another conveyor Highwall Miner A highwall mining system is typically used for surface Mining Equipment: AZ List for Maintenance Contractors
