The Assay Explains Surface Mining

High wall mining was initially derived from auger mining. Auger mining refers to mining coal at a high wall or cliff by drilling holes into an unprotected coal mineral seam and transporting it along an auger bit to the surface. High wall mining is a remotely controlled mining process that isolates coal from the base of an exposed high wall.

Auger effect | Auger electron, electron emission, atomic …

Auger effect, in atomic physics, a spontaneous process in which an atom with an electron vacancy in the innermost (K) shell readjusts itself to a more stable state by ejecting one or more electrons instead of radiating a single X-ray photon.This internal photoelectric process is named for the French physicist Pierre-Victor Auger, who discovered it in 1925.
