Coal Mining –The 2 Most Basic Techniques Of Extraction ...

10-04-2021  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. It is brought to the top using massive conveyor systems. Very deep coal mines are outfitted with elevator

Coal mining - Underground mining Britannica

Coal haulage, the transport of mined coal from working faces to the surface, is a major factor in underground-mine efficiency. It can be considered in three stages: face or section haulage, which transfers the coal from the active working faces; intermediate or panel haulage, which transfers the coal onto the primary or main haulage; and the main haulage system, which removes the coal from the mine.
