Shaft mining is a type of underground mining done by use of a mine shaft.
A mine shaft is a vertical or inclined passageway used to access to an underground mining facility. On the surface above the shaft stands a building known as the pit head (or poppet head), which historically contained a winding engine and in modern times contains an electric hoist controller. This raises and lowers the cage within the shaft. The cage serves as a lift for the transportation of minerals, equipment and workers.
The horizontal workings extending from the central shaft are called drifts, galleries or levels. This is contrasted to: Drift mining
