Adit information


Gated entrance of an abandoned adit near Medford, Oregon, United States

An adit (from Latin aditus, entrance)[1] or stulm[2] is a horizontal or nearly horizontal passage to an underground mine.[3] Miners can use adits for access, drainage,[4] ventilation, and extracting minerals at the lowest convenient level.[1] Adits are also used to explore for mineral veins.[1] Although most strongly associated with mining, the term adit is sometimes also used in the context of underground excavation for non-mining purposes; for example, to refer to smaller underground passageways excavated for underground metro systems, to provide pedestrian access to stations (pedestrian adits), and for access required during construction (construction adits).[5]
