The Grünewald mine was a non-ferrous metal ore mine in the Bensberg ore district in Overath in the Untereschbach district . A housing estate has formed over the years through mining. Today the district of Grünewald is located here .

history

Conrad Pörting unsuspected on behalf of the of the Belgian banker and industrialist in 1837 François-Dominique Mosselman founded " Société Anonyme des Mines et Fonderies de Zinc de la Vieille-Montagne " on 4 February 1856 called Buchholz Busch a mine field with the name Grünewald. The award took place on July 29, 1858 on lead ore .

From 1930 to 1978, the Lüderich mine pumped the sandy residues from its flotation via pipelines into the area between the village of Grünewald and the Großbuchholz farm , where the material was deposited on heaps .

Operation and facilities

The Grünewald mine field extended between the villages of Unterauel and Großbuchholz . No information is available about the work of the first period. In 1888 a tunnel was driven north in the valley floor west of Hof Daubenbüchel . A noble lead- gloss deposit was found at a length of 51 meters . A die was sunk over a length of 79 meters for further investigation work. This die was later extended for days and expanded into a machine shaft. At the same time as this work began on the southern side of the valley with the excavation of another tunnel, the so-called southern tunnel . During the further exploration work and the sinking of further dies, measures had to be taken in 1898 to improve the air circulation. A certain exhaustion of the deposit was already evident . In 1905 the company was stopped.
