A mine, i.e. an industrial facility for the underground extraction of mineral products, has three operating phases: it may be open or running, or closed or it may be a working museum.
In recent decades, however, they are often established immediately after mining ceases, creating some jobs funded at least partially by cultural tourism.
A few mines offer more authentic guided tours, by not using electric lights and equipping visitors instead with miners' lamps.
Preserved pit railways, needed to reach mining works deep within a mountain, are especially popular.
Examples include the Arthur Gallery (Arthurstollen) and the shale oil mine in Pertisau.
