The United Ruhrmannsbank colliery is a former hard coal mine in Witten- Borbecke. The mine was also known as the United Rohrmannsbank colliery . The mine emerged from the consolidation of several mines. The mine belonged to the Märkisches Bergamts district and there to the jury area Ostlich Witten .

Mining history

On February 3, 1824, the Ruhrmannsbank colliery consolidated with the Längenfeld Ruhrmannsbank No. 2 and the Sophia and Peter Caspar collieries . The newly founded mine was named Zeche Vereinigte Sophia & Ruhrmannsbank . In January of the following year, the Sophia tunnel was put back into operation and the Carl shaft began to be sunk . A length field was awarded in the period from November 24, 1826 to January 16, 1827 . In the same year the Zeche Vereinigte Sophia & Ruhrmannsbank was renamed to Zeche Vereinigte Ruhrmannsbank. In the mining area were two seams exist, one of which a thickness of 52 inches , has the power of the other seam is not mentioned. In the years 1830-1835 shaft Carl was promoting . On May 2, 1837, the Ruhrmannsbank No. 2 field was awarded. Schacht Herold was in operation from 1840 to 1847. In 1848 the mine was provided with a railway connection. There is evidence that the mine was in operation in 1850. Mid-1850s was the powerful 52-inch seam in Verhieb taken. In 1855 the mine field was amended by Sophia cleats solved . The Sophia tunnel was also used for extraction . The coal intended for railroad sales was transported from the tunnel mouth hole on a railroad to the Bergisch-Märkische Eisenbahn. This rail track was 65 laughs long and had a ramp. After 1858 the coal supplies were depleted and the mine was probably closed afterwards. In 1859, the square of Tuchsen below the bottom of the tunnel resulted in an overburden for the authorized Peter Caspar and Ruhrmannsbank. On March 12 of the same year, the United Ruhrmannsbank colliery consolidated with other collieries to form the United Borbecker Tiefbau colliery.

Promotion and workforce

Only edible coal was extracted from the mine . The first known production and workforce figures for the mine date back to 1830, when 86,032 bushels of hard coal were extracted. The workforce fluctuated this year between 17 and 28 miners . In 1835 100,446 bushels were mined. The probably maximum production dates back to 1838, with 33 miners, 32,077 Prussian tons of hard coal were produced. In 1840 81,512 bushels of hard coal were mined. In 1845 the production sank to 57,076 bushels. The workforce fluctuated this year between 14 and 26 miners. The last known production and workforce figures for the mine are from 1847, when 60,291 bushels of hard coal were extracted with 15 to 20 miners.
