Mining history

The mine in the upper Muttental was already in operation in 1787, and this year was also the likely start of production. On April 10, 1790 was carried out ceremony of the length field . The preparation for the dismantling was carried out by the external miner Kessel. From 1796 the mine was out of order. In April of the year 1837 the re-commissioning took place after a previous deeper solution by the Bommerbänker Erbstollen . In the same year, the barrel-length weather shaft was widened and deepened down to the bottom of the tunnel . In addition, the shaft was converted into the Ehrenfried Horse Gopel Shaft , and further dismantling began. There were two seams with different thicknesses in Verhieb taken. The thickness of one seam varied between 20 and 26 inches , and the thickness of the other seam varied between 48 and 54 inches. Led from the mine on day one Zechenweg to Witten-Elberfeld road. In April 1857 the mine was closed. On May 20, 1862, the consolidation to the United Bommerbänker Tiefbau colliery took place below the St.-Johannes-Erbstollen sole .

The first production figures come from the year 1837, 19,672 bushels were mined , that is 1,279 tons of hard coal . In 1840, 59,196 bushels (3,848 tons), the maximum production in mining history. The first workforce dates from 1845; between eight and sixteen miners were employed in that year. With this workforce 39,563 bushels (2,572 tons) of hard coal were mined. In 1847, 12-17 miners extracted 55,726 bushels (3,622 tons) of hard coal. In 1850, 12 miners extracted 2,340 tons. In 1855, 19 miners extracted 6,233 Prussian tons of hard coal.
