Adit
An adit is a type of entrance to an
underground mine which is horizontal or nearly horizontal. Adits are usually built into the side of a hill or
mountain, and often occur when a measure of
coal or an
ore body is located inside the mountain but above the adjacent valley floor or coastal plain. The use of adits is generally called
drift mining.
