The pit Bollenbach was a mine in Herdorf in district Altenkirchen in Rhineland-Palatinate .

Aisle means

The passage means of the pit were (information in the upper depths):

  • Main course I (16–40 m long, 0.8–5.5 m thick)
  • Main corridor II (38–69 m long, 2–9 m thick)
  • Main course III (70-75 m long, 1.5-9 m thick)
  • Main course IV (31–96 m long, 1–14 m thick)
  • Rothezecher Mittel (38 m long, 1–2 m thick)

The brittle mountains in the area of ​​the pit caused numerous accidents. The iron content in the Spateisenstein was 44.5%.

The Bollnbach mine was one of the most productive mines in Herdorf. The veins were up to 16 meters in thickness. It was awarded in 1746, and ore had already been mined here before. The corridors were opened up by several tunnels. The deep tunnel was created in 1747 and met the ore-bearing corridor after 33 years. Civil engineering was carried out from 1792 through a shaft on the bottom of the deep tunnel. The first art facility was installed in 1827. From 1866 civil engineering was carried out with the help of a steam engine . The old shaft (final depth 183.5 m) was created from 1866 and reached a maximum depth of 72 m in the same year. Bottoms were created at 35 m, 56 m, 87 m, 120 m and 157 m below the bottom of the tunnel. From 1870 it was the most productive mine in the area. In 1877 it was in 6th place in the entire Siegerland with its extraction and from 1885 it was the fourth largest mine in the Siegerland ore district . The production this year was 35,777 tons of ore. The second shaft, shaft I , was sunk in 1880 in the area of ​​today's sports field, as the old shaft broke below the 120 m level despite iron carpentry and could only be used up to there . Shaft I had a size of 4.03 m × 1.26 m and a depth of 526 m. The ore extraction was carried out at a speed of 4 m / s and a hauling rope with a diameter of 25 mm. In 1899 a preparation and the "Bollnbachsbahn" to the Friedrichshütte in Herdorf were built. Shaft II was built in 1897. It had a depth of 816 m and was in operation from 1907. In 1906 612  staff members worked in the mine. The mine had its heyday during the First World War . At that time the workforce numbered approx. 800 men. The ore deposits decreased with greater depth, so investigations were made to the pits Neues Glück and Heinrichssegen , but without obtaining favorable information. In the 1920s, an investigation section was laid on 550 m level to the already closed Hollertszug mine . However, the research work was also unsuccessful. No minable deposits were found on the 16th and 17th levels at 670 m and 770 m depth. In 1926 only 254 men worked in the mine. Production was stopped on November 23, 1926, and the mine was completely shut down on February 2, 1927. A total of 4.081 million t of iron ore was mined.

The nearby Stahlert mine in Herdorf, to which a connection was established after 1900, belonged to the mine . It was shut down in 1910.
