The quarry mine was one of many pits in the district of Müsen , today a district of Hilchenbach in the Siegen-Wittgenstein district . It was one of the most important of around 50 pits in the Müsen district .
Aisle means
The Brücher corridor served as a corridor . It was between 2 and 5 m (mostly approx. 3 m) thick and contained brown iron stone and, with increasing depth, spate iron stone with copper , lead and zinc ore . Between the tunnel and the pinge there was about 45 m of minable ore. 100 kg of copper pebbles contained up to 28% copper. The length of the corridor was 240 m on the deep tunnel floor. In 1864 the Brücher Eisenstein was described as the “stone richest in iron” in the Siegerland. The content of "carbonic iron oxide" was up to 80%.
history
It is likely that ore was dug before 1722, but it is only proven this year. The upper gallery reached 275 m in length this year. The middle tunnel , called “Oberste Brüche”, had a length of 272 m and hit the vein at a depth of 104 m. Between 1777 and 1824 a deep tunnel , the so-called Loher tunnel, was used. This was 502 m long, hit the ore vein at a depth of 148 m and in 1802 received a lining that is still preserved today. The entrance was closed around 1950. Mining was carried out using the broken storey construction method, which creates large underground cavities. The technology required the backfill of tailings, which were crushed in special mills. The backfilling created five over 40 m deep pings ( Brücher incursions ), the steep slopes of which were flattened by blasting in the 1960s.

A later day shaft led to a depth of 172 m, a blind shaft built in 1867/68 to a depth of 294 m. In 1885 the depth was reached. In 1869 a twin hoisting machine and a drainage machine were installed in the shaft . Levels were created at 42 m, 84 m, 125 m, 167 m, 209 m, 251 m and 294 m depth.
In addition to the amounts of iron ore given in the table, smaller amounts of copper and lead ore were mined. In 1863 61 t of copper ore were mined, in 1865 it was only 7.1 t, a year later 159 t. In 1867, 377 tons of lead ore were also extracted from the earth. At peak times, up to 16,000 t of iron ore and around 161 t of copper ore were mined per year, the total output was around 313,000 t of iron ore.
After the mine was closed in 1891, the Stahlberg mine took over the mine and leased it to private individuals. Experimental work and minor dismantling was carried out in the years 1899–1901, 1906–1908 and again between 1923 and 1925. From 1934, miner Otto Rompf managed the mine until 1941. Rompf and his son extracted 6,000 t of iron stone between the upper and deep tunnels. Funding has not been granted since 1941.
