Coal mining
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit ...

Cet article dresse un bref historique des machines d'extraction et rappelle les grandes étapes de leur évolution technique. Les résultats des recensements du patrimoine minier réalisés dans le bassin houiller lorrain et dans le bassin potassique alsacien ont permis de distinguer les éléments représentatifs et remarquables de ce patrimoine méconnu et insuffisamment considéré.
Environmental Damage
All of the stages of mining, refining, and disposal come with unique issues. Mining. The physical process of removing the ores from the ground is disruptive to the environment. Most rare earth elements are mined through open pit mining, which involves opening the surface of the earth using heavy equipment and machinery. Creating this disruption ...

D = Workpiece diameter (mm) Q = Material removal rate (cm3/min) R a = Surface roughness (μm) re = Nose radius (mm) Milling Legend v c = Cutting speed (m/min) n = Spindle speed (rev/min) v f = Feed speed (mm/min) a p = Axial depth of cut (mm) a e = Radial depth of cut (mm)
Environmental Risks of Mining
Environmental Damages of Mining. Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount ...

What is Underground Mining? (with pictures)
Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ore inside.
