Mining history
The princess tunnel, also known as the princess upper tunnel, was probably built around 1740. The tunnel mouth hole was located in Ehrenfeld at the intersection of Kulmer Strasse and Friederikastrasse today . The tunnel was 400 meters to the southeast ascended . At that time the mine was a sovereign colliery that was leased to private companies . In 1749 the mine was taken over again on a sovereign account. In the same year the tunnel was abandoned due to insufficient construction height . A new tunnel was set up 160 meters to the northwest. This princess deep tunnel, also known as Princess Erbstolln, was set about six meters lower than the upper tunnel. A depth gain of five meters was achieved through the tunnel. The tunnel mouth hole was located south of today's Graffring. The tunnel was driven under the upper tunnel. The mine was in operation from 1750. As with the galleries of the old man had been hit, the mine was in the years 1754-1755 in deadlines set. From 1758 the mine was back in operation.
In 1761, a coal seam 2.5 feet thick was hit . The coal seam was named Friederica. In 1762 the colliery should be solved deeper by an eastern wing location of General Erbstolln . No results are known in the documents about the results of this investigation . In 1868 the coal was extracted in the substation. There were also difficulties in selling the coals. In 1770 the excavation was carried out using a die below the bottom of the tunnel. In the same year a disturbance was approached in the eastern part of the field after an approach length of 500 meters . For this reason, the mining in the east was stopped. The mine was again placed in time limits. In 1772 the Friederica Erbstolln was driven east of this fault . In 1784 the princess tunnel and the associated shafts were largely broken . In 1822 the legitimate was measured . After that, the mine was still within deadlines. On August 17th, 1846, the square was awarded to the princess . The field had a size of 0.8 km 2 and was reserved for the state. In 1852 the Princess mine was privatized and sold to the Friederika mine .

Remarks
- ↑ A "sovereign colliery" was a mine that was owned by the royal family. Thus, the Prussian king was practically the main trade of such a mine. (Source: Kurt Pfläging: Stein's journey through coal mining on the Ruhr. )
