What is Underground Mining? (with pictures)

One major need with underground mining is ventilation. Ventilation is necessary to remove dust, byproducts of combustion, and byproducts of explosions, along with gases which may be trapped in pockets inside the Earth. Proper support to prevent collapses is also rather important, as are redundant safety systems including alarms for workers, evacuation shafts, emergency lighting, and so forth

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 long wall, which is a shear blade that

Digging deeper: Mining methods explained Anglo American

Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. The entry from the surface to an underground mine may be through a horizontal or vertical tunnel, known as an adit, shaft or decline. Underground mining is practical when: The ore body is too deep to mine profitably by open pit. The grades or quality of the

Underground hard-rock mining

Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead.It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies.

Underground soft-rock mining

Underground soft-rock mining is a group of underground mining techniques used to extract coal, oil shale, potash, and other minerals or geological materials from sedimentary ("soft") rocks.
