The Graf Wittekind colliery is a former hard coal mine in Syburg . The mine mined the Sengsbank seam in the higher parts of the Syberg that had not been reached by the Schleifmühle colliery . After its active use, the mine was converted into a visitor mine .

Mining history

Mining formalities

On January 13th, 1858, the mining invalid Wilhelm Rüttler submitted a prospecting application to the mining authority. He dug a 2½ Lachter deep shaft . The starting point of the mining shaft was 144½ Lachter from the southwest corner of the castle ruins. On April 6 of that year, which was by the same man presumption lodged with the Mining Authority. The assumption was made under the name Graf Wittekind on a free coal seam and on a 20 inch thick coal iron stone seam . On May 26th of the same year the site was measured by the mine surveyor C. Crone . On October 5th, 1860, a square was awarded . The award was made for the mining of hard coal, the award of the iron stone field with the name Hohen Sieberg Beilehn was rejected by the mining authority. The reason for this was that the Eisensteinfeld Hohen Sieberg Beilehn collided with Eisensteinfeld Schloß Syburg . This Eisensteinfeld had already been awarded to Johann Caspar Harkort on April 28, 1853. But even the mining of hard coal could not take place at first. The reason for this was that there was no agreement with Johann Caspar Harkort. This ultimately led to the fact that the owner of the authorized Wilhelm Rüttler sold 122 Kuxes from his Kuxen to the brickworks owner Carl Blankenagel zu Höing near Hagen on March 28, 1868 . Wilhelm Rüttler kept six of the Kuxe in his possession. Negotiations with the trades began on April 8 of the same year . Following these negotiations, the mine was put into operation in the same year.

business

In 1868 a start was made in a former mining area of mine Schleiffmühle tunneling to operate. The start of operations at the Graf Wittekind colliery was reported to the mining authority on April 9 of the same year. An old tunnel was cleared for extraction . In addition, a mining section that connected to the north-east of the conveyor tunnel was cleared and partially re- excavated . At the end of this mining section there was a brake mountain that had previously been used for mining by the Schleiffmühle colliery . So that the Bremsberg could be used again for mining, the fine coal on the lying surface was also removed. In addition, this pit was also cleared and broken 0.5 meters higher. The resulting rock was built into the Bremsberg as a dry stone wall, which gave the Bremsberg better stability. The entire Bremsberg was given a rectangular extension. Due to the width of the brake mountain, each cap was supported with three stamps . The dimensions made it possible to equip the Bremsberg with a double-strand conveyor. The conveyance took place in the conveyor tunnel by means of conveyor vehicles moving on rails . In the years 1869 and 1870 the mine was put in time limits .

Due to problems with the property owner, the actual dismantling could not take place until the middle of 1871. This led to the owner of the mine Carl Blankenagel selling 114 of his Kuxe. Friedrich Dittmar zu Annen and the brewery owner Carl Dellmann Königs-Steele each acquired 57 Kuxe. As a result of this sale, four trades were in possession of the beneficiaries from this point in time. After the land negotiations on June 30, 1871, had no results, the four trades applied for another negotiation with the responsible miner . In this negotiation, an agreement was reached and dismantling could begin. In the summer of 1871 the mine was put back into operation. In the broken pillar construction , Graf Wittekind No. 1, 2 and 3 were dismantled in the direction of the tunnel mouth holes . In the same year a shaft was sunk .

In 1873 there were a total of five tunnels . In 1878 the mine was again put into time limits. The Graf Wittekind colliery was shut down due to inefficiency before 1900. During the French occupation in 1924, unauthorized mining was carried out in tunnel 4 . When the Hengsteystraße was built between 1928 and 1929, part of the coal seam was exposed. The exposed coals were used to heat the steam excavators . In the years 1940 to 1945, tunnel 4 was used as an air raid shelter. From 1945 to 1948 there was probably unauthorized mining in tunnel 4. Until 1977, the tunnel systems were still freely accessible to everyone. In 1977 the tunnel mouth holes of the conveyor tunnel and tunnel No. 4 were filled in by the city of Dortmund for reasons of liability.

The tunnel system

Map of the colliery

The tunnel system consisted of several tunnels. Tunnel 2 was driven between 1858 and 1873. The cleat 3 has ascended 1858 he was to 1878 to promote use of the above lying coal. There was a reel lift right next to the tunnel mouth hole, on which the coal was pulled up to the mine house above. The tunnel 4 was created in 1858, it served until 1878 to mine the coal reserves above. The tunnel was driven cross-cut and was provided with a water slurry up to the tunnel mouth hole , which was lined with half-shell-shaped wood. The water slope, starting from the tunnel mouth hole, was designed to rise slightly to allow the pit water to drain away . In tunnel 4, the coal that was mined in tunnel 3 was also removed. For this purpose, the coal was first transported from tunnel 3 to tunnel 4 via an underground conveyor mountain and then conveyed above ground. The tunnel mouth hole is located on the Syberg near the present-day Kaiser Wilhelm monument. The lowest tunnel of the Graf Wittekind colliery is the conveyor tunnel, which was used until 1878 to extract coal from the stocks above. The tunnel was probably already excavated and used by the Schleiffmühle colliery .

Promotion and workforce

The first production figures of the mine come from the year 1868, in that year 55 tons of hard coal were produced . The first workforce numbers are named for the year 1871, in that year, ten miners extracted 1287 Prussian tons of coal. In the following year, five miners extracted 540 tons of hard coal. The colliery's maximum extraction was achieved in 1873 with four miners; 609 tons of hard coal were extracted. In 1875 the production sank to 310 tons, this production was done by two miners. The last known production and workforce figures for the mine are from 1876, in that year 72 tons of hard coal were extracted with two miners.

Preparation for subsequent use

A large amount of work had to be carried out in order to re-open the tunnel system for inspection. On November 17, 1986, tunnel No. 4 was opened on a trial basis. For this a small shaft was dug manually on the solid slope. The subsequent exploration of the tunnel system revealed that the tunnel system was worth a monument. Starting in 1987, three tunnels and other mine workings were exposed and cleared up again . From August 19, 1989, the conveyor tunnel was also excavated. The mouth of the conveyor tunnel was provided with a brick entrance and a lattice gate. In order to continue using the tunnel systems, several tons of tailings had to be loaded manually, transported out of the mine building with wheelbarrows and unloaded on the tunnel dump. Some of the pits also had to be expanded and the hanging wall torn down. In almost all of the pit works, the wooden lining , which was in a very poor condition due to rot and fungal attack, had to be replaced. A recovery box was placed in this area so that the transition from the high to the low part of the conveyor mountain, which was at risk of breaking , could be stabilized . After this work had been completed by 1997, the tunnel system was approved for visitors.

Current condition

In 1997 the Graf Wittekind visitor mine was put into operation. There is also a ping available from the Graf Wittekind colliery . The pinge is located on the Syberg in Syburg on Hohensyburgstrasse, near the Kaiser Wilhelm monument. The pinge is station 19 on the mining circuit.
