    17 hours ago· What is Strip Mining? Surface mining, counting strip mining, mountaintop removal mining and open-pit mining, is a wide classification of mining where soil and rock covering the mineral source (the ‘overburden’) are gotten rid of, unlike underground mining (or deep mining) where the overlying rock is kept in place, and the mineral is taken out through shafts or tunnels.Coal Mining –The 2 Most Basic Techniques Of Extraction,The second fundamental method of extracting coal is underground mining. This technique is used when the coal is buried deep inside the earth. The machines used for this type of coal extraction can excavate at depths of more than thousand feet. The coal itself is cut out from rocks using machinery.

  • Strip Mining: A Destructive Way of Coal Extraction

    Mar 12, 2017· Strip mining also uses significant amount of water to suppress dust. Overall, the impact of coal mining in general on water is worth noting: it is not just the water used and depleted during the extraction process, but also the amount of water needed for converting coal into energy.Strip Mining an overview ScienceDirect Topics,Andrew P. Schissler, in Encyclopedia of Energy, 2004. 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.

  • Surface Mining Techniques used in the Oil Sands Oil

    Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reservesMining Methods Flashcards Quizlet,a method of stope mining that allows extraction of vertical deposits that are surrounded by competent rock mass (rock that can support itself) Quarrying similar to open pit mining or strip mining, but for rock mines (non-coal and non-metal)

  • Underground Mining Methods — New Pacific Metals

    In 2005, only 17% of metal mines were underground operations (Raw Materials Data, Stockholm 2010) but there are many instances where underground extraction of minerals is more cost-effective than surface mining, typically when the given ore body is high grade or very deep.Coal Mining –The 2 Most Basic Techniques Of Extraction,1.
