The Actual Difference Between Surface and Underground Mining

In surface mining, the ore is accessed directly from the Earth’s surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface.

Coal mining - Wikipedia

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 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

Coal Mining: How Is Coal Mined? - Science ABC

07/01/2021  Surface mining and underground mining are the two major schools of coal mining. To qualify for surface mining, the coal deposits must be within 50-80 meters of the surface. The job of a miner primarily involves removing ‘overburden’— rock, soil, trees etc. – that mix with the coal deposits and cover them near the earth’s surface. They need to clear this material so the layer of coal ...

Commonly used mining techniques to extract coal IEA ...

25/01/2018  Surface mining and deep underground mining are the two main methods of mining coal. Depth, density, and thickness of the coal seam are the factors that are taken into account while selecting the mining method for coal extraction. However, many coals extracted by using these two methods need washing in a coal preparation plant. Surface mining: The mining technique is used when the coal

Surface mining - Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Surface mining – strip, open pit, mountaintop removal ...

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 ...

Modern day mining takes a much safer approach then their riskier predecessors with coal now extracted through two main methods, open cast or surface mining and underground mining. Open cast mining is designed in order to extract coal which resides close to the surface and involves the removal of overburden in order to reach the coal. This overburden is stored until needed again when the open ...

Coal National Geographic Society

22/12/2012  Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining. In surface mining, workers simply remove any overlying sediment, vegetation, and rock, called overburden. Economically, surface mining is a cheaper option for extracting coal than underground mining. About two and a half times as much coal can be extracted per worker, per

Earth Science: Underground Coal Mining.

14/03/2013  There are 5 types/ways of underground coal mining. 1: Drift Mining. Drift Mining is possible where the coal seam intersects the surface. The mine enters the seam in a horizontal direction following the coal. A drift may or may not intersect the ground surface. This kind of mining is done when the rock or mineral is on the side of a hill. The advantages is drift mining is much cheaper and much ...
