The United Henriette colliery in Eichlinghofen is a former hard coal mine . The mine was created from a consolidation of the two authorized persons Henriette I and Henriette II. The mine was part of the Dortmund mining district .

history

Henriette's first years

Lochstein Henriette II

Not much is reported about the Henriette colliery, the colliery was already operating as a tunnel operation before 1831. In 1841 6,058 bushels of hard coal were mined. In the following year, the mine was no longer mentioned in the documents. In 1846 the mine was back in operation. On August 21, 1848, the Längenfeld Henriette I and the Geviertfeld Henriette II were awarded . In 1856 it was consolidated into the United Henriette colliery. In the same year the mining company Potsdam was founded as the owner of the United Henriette colliery.

The other years United Henriette

In 1856, after the consolidation, civil engineering began and the Sanssouci shaft began to be sunk . The shaft first had to be sunk by eight ponds using chalk marl. This area had to be walled watertight . In 1857 the Jacob Erbstollen was taken over and the Henriette III mine was acquired. That same year, the shaft Sanssouci reached at a depth the 17 meters carbon . A seam 24 inches thick was cut at a depth of ten pools. The seam sloped 66 gons south. In 1858, the bottom of the tunnel was set at a depth of 52 meters (+65 meters above sea ​​level ). During the sinking work there was no notable water inflow, two seams were penetrated. One of the seams was 62 inches thick and the other seam was 15 inches thick. Both seams sloped south at 66 gons. In 1859 (+12 meters above sea level) was the first at a depth of 105 meters sole recognized. The crosscuts to the south were driven on both levels . Two seams were opened up with both crosscuts. One of the seams was 20 inches thick, the other seam was 60 inches thick. The seams dipped 66 gons south. In both seams, the excavation of the basic sections began. In the same year, the Geviertfeld Henriette III was awarded and funding began. In 1860, a 16-inch thick seam was driven through on the underground level with the southern crosscut. When driving the crosscut to the north, a 38 inch thick seam was opened up, which had a mining portion of three inches. During the further excavation of the invert sections, some significant faults were encountered in the seams that were worth building . The water inflows were relatively small at only one cubic foot per minute.

In 1861 a conveyor tunnel was added to the Barop train station and the Sanssouci shaft was sunk down to a depth of 56 Lachtern . The conveyor tunnel was excavated to a length of 52 puddles in the same year. The crosscuts on the foundation slab were driven further in both directions. In the same year, Henriette III consolidated into the United Henriette mine. This year, the construction of the device was started on the underground level in the seams that had already been developed . In the following year, too, the cross passages on the underground floor and the weather floor were driven further. The northern cross passage on the first building level reached a length of 109 pools and the southern cross passage on the same level reached a length of 43 pools. The northern cross passage on the weather bed reached a length of 96 laughs. The conveyor tunnel to the Barop station was driven further by means of an opposite site drive. The breakthrough occurred towards the end of the year . In 1863, the eastern fault was reached and penetrated both on the building base and on the weather base with the respective northern cross passage. During the excavation there was only a small amount of water. With the crosscut on the building base, seam No. 8 approached. The seam was twenty-four inches thick. In seams No. 1, 6 and 8 the alignment and fixture work continued. In 1865, the crosscuts on the weather bed and the crosscuts on the building floor were driven further north. During the drive, a seam with a thickness of 92 inches including 22 inches of tailings was approached. It was assumed that the seam was the thick cherry tree seam. In 1866 the Sanssouci shaft was sunk deeper again. In the following year, at a depth of 147 meters (−30 meters above sea level), the 70 Lachter level was set and aligned . In 1868 there was a mine fire , due to the mine fire part of the mine field was abandoned. The following year, only insignificant amounts of coal were extracted from the mine. On the first building level, the main cross passage at a distance of 441 3/4 Lachter from the shaft cut through the Stockumer Hauptgebirgssattel.

The last years as United Henriette

In the middle of 1870, the United Henriette colliery became insolvent and bankruptcy proceedings were initiated, but the colliery was still in operation. In 1871, mining was initially carried out on a small scale , and the United Henriette colliery was auctioned on May 24 of the same year. The Holthausen colliery and the United Hummelbank colliery were acquired in 1872, but both mines remained independent. In addition, the Augenschein and Haberbank fields were acquired. In the spring of 1876 the pit sank due to heavy rainfall and had to be swamped . In 1877, mining was carried out in the northern part of the Holthausen field and in the Hummelbank field. In the same year several day breaks occurred , as a result of which the northern field was dammed against day water . In 1878 the Sanssouci shaft was sunk deeper again. In the following year, the third level, also known as the 90-Lachter level, was set at a depth of 190 meters (−73 meters above sea level). Due to strong water inflows, the tunnel construction in the north field was stopped in 1881 . In 1883, all authorized persons were merged and continued under the name Baroper hard coal mines.

The further operation as Baroper hard coal mines

In 1883, the Holthausen , United Hummelbank and United Henriette collieries were merged under the name Baroper Steinkohlenbergwerke. The pit field of the Baroper coal mines was in the city of Dortmund-Barop-Eichlinghofen. The three mines had previously been operated separately under the Bergisch-Märkischer Verein. The beneficiaries comprised the United Hummelbank and United Henriette fields and the four Holthausen fields and had a size of 8.5 square kilometers. The Hummelbank shaft, which had been closed since 1881, the Holthausen shaft (shaft 1) and the Henriette shaft (shaft 2) were available as shafts. In the Holthausen shaft, the 3rd level was present at a depth of 196 meters (−97 meters above sea level), in the Henriette shaft the 3rd level was at 190 meters (−73 meters above sea level). The Henriette shaft was used for dewatering , weather management and as a production shaft, while the Holthausen shaft also served as a production shaft. In the same year, a coal washing plant was built at the Henriette shaft . In 1884, the entire production was relocated to the Holthausen shaft, from then on the Henriette shaft was only used for drainage and for private use. In the same year, a coking plant was put into operation at the Holthausen shaft . In 1885, the Holthausen shaft began to be deepened. In September 1887 bankruptcy was filed. In 1888, the 4th level was set in the Holthausen shaft at a depth of 296 meters (−197 meters above sea level). In the same year a weather shaft was opened north of the Holthausen shaft. On August 25 of the same year consolidation at the Kaiser Friedrich mine took place.

Promotion and workforce

The first known production and workforce figures come from the year 1866. At that time, 292 miners were employed in the mine, who produced 173,186 Prussian tonnes of hard coal . In 1870, 32,815 tons of hard coal were mined with 247 miners. In 1874 the production rose slightly to 49,647 tons of hard coal, this was provided by 306 miners. In 1877, production rose again slightly to 50,982 tons of hard coal, and the workforce decreased to 239 miners. In 1880, 347 miners extracted 74,908 tons of hard coal. The last known production and workforce figures for the mine are from 1881, in that year, with 355 miners, 88,792 tons of hard coal were extracted. This was also the maximum production of the mine.

The first known extraction and workforce figures for the Baroper hard coal mines date from 1883, in that year, with 522 miners, 96,708 tons of hard coal were extracted. In 1885 production rose to 159,590 tons of hard coal and the workforce rose to 695 miners. The last known production and workforce figures for the mine are from 1888, in that year 78,447 tons of hard coal were extracted with 303 miners.

Current condition

The northwestern remnant of the interrupted railway embankment at the level of the Rüpingsbach

Today, part of the south campus of the Technical University of Dortmund (south of Baroper Strasse) is located on the mine site of the United Henriette colliery . The shaft, closed with an inconspicuous cover, can be found in a meadow on the footpath between Campus South and the “Am Gardenkamp” bus stop.

At the former intersection with the Rüpingsbach , the route of the old horse-drawn tram is still clearly visible. The riverside path, which was laid out some time ago, leads directly along the southeastern remainder of the interrupted railway embankment.

A perforated stone , which is located in Dortmund-Barop on Hugo-Heimsath-Straße, is still reminiscent of the Henriette colliery. The perforated stone is located in a wall at the height of house number 48 and comes from the Henriette colliery. The perforated stone probably stood on the ground earlier and was only inserted into the wall when Hugo-Heimsath-Straße was being built on. This perforated stone is registered as a monument in the list of monuments of the city of Dortmund .
