The Große Burg composite mine was located in the local area of Altenseelbach , a district of the municipality of Neunkirchen in the Siegen-Wittgenstein district . It was one of the most important in the free area and the largest in the local area of ​​Altenseelbach.

Aisle means

Before the consolidation in 1917, the corridors of the pit were only the corridors of the Alte Burg , Neue Burg and Burg pits .

The three passageways in the Lohmannsfeld mine mainly led to Spateisenstein , fused with quartz, lead luster and zinc blende , with minor copper and sulfur pyrites . 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.

The Gute Hope pit had two corridors that were up to 60 m long and were divided into an eastern and a western corridor. The corridors were between one and two meters thick and filled with spate iron stone with lead and zinc ores. After the depth, the thickness decreased to 0.7 to 1 m. The Silberart mine had a 16 m long, 0.8 to 1 m thick passage means made of zinc blende and a second means with a length of 12 m and a thickness of 0.3 to 0.5 m.

history

The amalgamation of the Große Burg was established on August 29, 1838 from the pits Alte Burg , Neue Burg and Burg . An experimental tunnel was created. Between 1880 and 1885, 424 t of zinc blende and 149 t of lead ore were mined.

In 1910 a tunnel collapsed several meters, four miners suffocated. In 1911, the mine decided to purchase parts of the cable car that was no longer needed on Pfannenberger's agreement . In 1917 the mine consolidated with Lohmannsfeld , Gute Hope and Silberart . However, no more ore was mined until 1923.

Civil engineering on Lohmannsfeld

The Mannseifenschacht was sunk in the Lohmannsfeld pit from 1860 onwards and had a depth of 419 m, at the same time a blind shaft was sunk up to 137 m in the middle Wilhelmstrost. The total depth of the pit was 895 m and could be reached via a blind shaft (the first level was the 350 m level). The shaft was equipped with a 14 hp steam engine and 3 dewatering machines, two of which were 40 hp above ground and a 32 hp underground. The production took place through the deep tunnel of the mine. The following levels of the pit are known: 130 m, 160 m, 200 m, 230 m, 270 m, 310 m, 350 m, 390 m, 430 m, 480 m, 530 m, 580 m, 630 m, 680 m, 730 m, 780 m, 840 m.

There were plans to sink the shaft to a depth of 1,500 meters and thus mine ore for another 15 years, but these plans were never realized. The ore was then to be transported via the Silberart mine to the Gold mine and on to the San Fernando mine in Herdorf .

In 1932 an attempt was made to create a 1.5 km long cross passage to the Knappschaftsglück mine in Neunkirchen , but it was abandoned in 1935. A year later, the Siegen flotation company took over the operation of the mine. It had its heyday in the 1940s, in 1943 70,258 t of iron stone were mined . A tunnel served to develop the upper pit area. In 1945 ore mining was stopped and in 1959 it was finally shut down. 576,483 t of iron ore were mined in the mine, with Lohmannsfeld together 799,969 t. In 1953 the mine was attached to Erzbergbau Siegerland AG . This later carried out investigations in the mine area. However, funding was no longer started. The ore processing plant was demolished in 1962.

Flotation plant

A flotation plant was built in 1925 and was in operation until 1955. Between 1935 and 1952, 12,309 tons of zinc , 3,902 tons of lead , 4,643 tons of copper were extracted here, as well as 2.5 tons of silver per year, a few tens (10) kg of gold per year. In 1951 and 1952 the heaps of the surrounding pits Ludwigseck , Gleiskaute , Junge Löwe and Silberart were processed. From 1952 heaps from pits like Anxbach bei Neuwied were processed.

Consolidation pits

  • Alte Burg , awarded again in 1880; Production in 1867: 1.6 t of zinc blende
  • Good hope , awarded before 1885. In 1885, 26 t of zinc ore and 16 t of lead ore were extracted through a 1008 m long deep tunnel and a small machine shaft. A wet mechanical treatment was located on the mine dump. This consisted of a washing machine with separation drums and manual sieves. There were also two upper tunnels . The mine emerged from a consolidation with the pits Carl , Friedensfürst , Silberquelle and Gute Hope III . The passage means consisted of two means up to 60 m long and 1–2.5 m thick, which were filled with spate iron stone with lead and zinc.
  • Lohmannsfeld , awarded around 1700
  • Silberart am Hohenseelbachskopf, awarded around 1855; shut down in 1880. The deep tunnel in the Seelbachtal was built in the 1850s and was 380 m long.
