The Lohmannsfeld mine was located in the Neunkirchen district of Altenseelbach in the Siegen-Wittgenstein district . Until 1917 it was the largest independent mine in the village, with the Great Castle pit being one of the largest in the open ground .
Vein resources and ore deposits
Three main course remedies mainly led to Spateisenstein , fused with quartz, lead luster and zinc blende , copper and sulfur pyrites also occurred to a small extent . These gang means were
- the Mannseifer corridor with a length of 25 to 50 m,
- the Lohmanner Gang with 25-50 m length and
- the Wilhelmstroster corridor , 20–45 m long.
In addition to the passage means the corridors were Young Lohmann , Kreutz transition , copper strand as a transition debris and were quite insignificant. 100 kg of lead ore extracted contained an average of 30–108 g, rarely up to 150 g of silver.
history
A trade union from Dillenburg mined lead ore on the Wilhelmstrost Mittel in 1700 . A consolidation of the gang remedies Wilhelmstrost , Lohmann and Mannseifen followed later . The deep tunnel , called Wilhelmsgruß , was located in the Seelbachtal and had a depth of 83 m underground.
A blind shaft in the middle of Wilhelmstrost was sunk from 1860 to 137 m below the tunnel floor; it was equipped with a steam engine with 8 hp, which was later replaced by a 30 hp engine. In 1885 the shaft reached a depth of 203 m, floors were already struck at 26, 52, 78, 100, 135, 160 and 200 m. At the same time, the man soap shaft was sunk from above ground to a depth of 419 m. He was equipped with a 14-horsepower steam engine and three water amusement machine , of which two 40-PS days and a 32-PS-machine underground to 125-m level as a reserve. Funding was provided through the pit's deep tunnel . The total depth was 780 m.
In 1885, the processing consisted of a steam engine, a water wheel, a stamping mill, a rolling mill, several separation drums and setting machines as well as pumping ovens. There was also a repair shop and a laboratory for determining the metal content. In 1917 the Great Castle pits were merged from the Lohmannsfeld , Gute Hope and Silberart pits . In 1918, the German-Luxemburgish Mining and Hütten-AG took over the Kuxen majority of the mine. In 1948 the production was stopped.

The production of the mine hardly increased with the general upswing. While 299 t of lead ore were mined in 1859, it was already 549 t in 1864, but a year later again 287 t and in 1870 only 166 t. In addition to lead ore, about twice the amount of zinc blende was mined annually, in 1863 it was 777 t, in 1864 908 t and in 1865 762 t. In contrast to lead ore production, zinc blend production decreased from the 1870s to 1885 to 307 t of zinc ore, while lead ore production remained at 342 t and rose to 976 t by 1894.
Iron ore extraction was the strongest on Lohmannsfeld , although iron was actually only a by-product here. It was first mentioned in the statistics in 1863. In 1866, 2,628 t of Spateisenstein were mined, by 1885 the production increased to 3,470 t. The highest production in 1894 was around 11,000 t. In the years 1909 and 1910 there was little or no iron ore extraction. In addition to lead, zinc and iron ores, small amounts of copper ore were also extracted; in 1885 it was 101 t. The total production of Lohmannsfeld was 223,486 t of iron ore.
