Geology

At Mühlwand socalled Alaunschiefer (alum schist) was mined, a rock which was used for the production of sulfuric acid and other sulfur based substances. The rock is a typical schist with an high amount of pyrite and various hydrocarbons. Pyrite (FeS2) is the orign of the sulfur.


Description

Since 1691 the alum shists were mined in Mühlwand, at first in an open cast or quarry. But after some time the open cast had a considerable depth, and because of the surrounding property owners there was no possibility to extend the open cast. Additionally the water in the pit was a serious problem, so the miners had to construct an adit, which would allow the water to flow out of the quarry. As a result the mining went underground, and the former open cast above was used to store the debris of the mining process.

The underground mining ended in 1827, a time before the most important inventions in mining technology had not yet happened. SO the whole mine was constructed completely by the work force of the miners, dug by hand with Schlägel und Eisen (hammer and chisel). So this show mine offers a view into the mining techniques of the early 19th century.

The show mine was opened in 2002 and is managed by the non-profit Tropfsteingrotte Alaunwerk Mühlwand-Reichenbach e.V.. It is open all year on weekends and has some 4,000 visitors per year. A flood of melting water caused a avalanche of mud and debris flowing into the show mine. The show mine had to be closed. The mine was cleared by the work of volunteers and two long time unemployed who were payed by the employment agency. They manually removed some 100m³ debris from the passages and the show mien could be reopened in April 2011.
