The uranium mining waste stream was from the two inspection galleries, the church Heimer tunnel , named after Franz Kirchheimer , the President of the Geological Survey of Baden-Wuerttemberg, and the sour Bosch tunnel , existing mine to investigate a uranium deposit on the western edge of the northern Black Forest in Baden-Baden district Oberbeuern in Baden -Wuerttemberg .
Prospecting
As early as 1951, the news magazine Der Spiegel reported on the uranium deposits in the Black Forest. In March 1973 the Baden-Württemberg Ministry of Economic Affairs granted the mining company Saarberg-Interplan Uran GmbH permission to search for uranium and thorium ores in an area of 953 km² . The prospecting permit was converted into a prospecting concession in 1975, which was limited to 1984.
In April 1974, the Kirchheimer tunnel was started to be excavated, it reached a length of 150 m. In 1975 the Sauerbosch tunnel was driven about 40 m deeper , and both tunnels were connected with a cut .
The prospecting showed that the uranium mineralization in the deposit cities of Müllenbach is bound to the Upper Carboniferous, carbonaceous mudstones and arkoses and that it is the second most important uranium mineralization after the Krunkelbach mine in the Black Forest.
Prospecting revealed a supply of around 1500 t of uranium (V, VI) oxide .
Mining was stopped in 1984 due to some fierce resistance from the city of Baden-Baden and from environmental associations. The former mining area has been part of the Sauersbosch, Pfrimmersbach- and Märzenbachtal nature reserve since 2013 .
Contaminated sites
The rock from mining (500 m³) in Sauersboschtal (6000 m) and Müllenbachtal stockpiled and is a not to be underestimated legacy.
