The Caroline colliery is a former hard coal mine in Bochum- Cornharpen. The mine was in operation for almost 70 years, with a few brief interruptions. The name "Caroline" is probably derived from Friederika Caroline Amalie Müser, the wife of Friedrich Wilhelm Müser (founder of Harpener Bergbau AG) and mother of the later General Director Robert Müser .

history

The beginnings

1856 Teufbeginn of was shaft Caroline 1. The shaft was the Berechtsame full moon, east of the present Kornhapener road between the railways. The shaft was located 500 meters east of the Prinz Eugen mine. 1857 at a seigeren depth of 44 meters (m +67  NN das) Carbon achieved. In February 1859, the sinking work was postponed at a depth of 56 meters due to lack of funds. On April 6, 1870, the Caroline field was separated from the full moon authorization and ownership changed to Harpener Bergbau-AG. The field was aligned by the Prince of Prussia colliery . 1871, the sinking work in the shaft Caroline 1 were further continued, and the 1 at 83 meters  sole attached. In 1872 the second level was set at a depth of 148 meters, and mining began in the same year .

The other years

In 1873, mining began in the Caroline 1 shaft. The coking plant was also put into operation. In 1874 a large part of the field from the Prince of Prussia colliery was taken over. The following year, the Caroline 1 shaft was sunk deeper and in 1876 the third level was set at a depth of 206 meters (−93 m NN). In 1878 the breakthrough took place on the third level with the Prince of Prussia colliery. On July 6, 1881, a fire broke out over the course of the day, in which the coal washing machine and the headframe were affected. As a result of the fire, operations were stopped for three months. In 1882 an iron headframe was erected and the shaft sunk deeper again. In 1883 the 4th level was set at 266 meters (−150 m above sea level) and the 5th level in 1885 at 351 meters (−235 m above sea level). In 1892 the construction field included the Harpen, Neumond and Sirius fields, as well as parts of the Prince of Prussia, Vollmond, Klothkamp and Caroline fields. In 1894 the breakthrough took place with the weather shaft of the Zeche Prinz von Preußen, the weather of the mine Caroline was also weathered through this shaft .

In 1897 the wash house was rebuilt above ground . Instead of the team pool used until then, a corresponding number of showers was installed. At that time the mine was part of the southern Bochum mining area . In 1901, the sinking of shaft 2 began. The shaft was sunk next to shaft 1. In 1903, shaft 2 reached the 5th level. In 1904, the 6th level was set in shaft 2 at a depth of 463 meters (−352 m above sea level) and the mountain conveying system started up. Shafts 1 and 2 were used for ventilation , rope travel and shaft conveyance . In 1905, a joint venture with the Prince of Prussia colliery was established, and coal was extracted via shaft 2. In the following year, coal processing was taken over by the Prinz von Prussian colliery. In 1907, shaft 1 was used as a weather shaft for both shafts. On April 1, 1910, a briquette factory was put into operation, which was shut down again in mid-1915.

The last few years

In 1921 the Prinz mine was taken over by Prussia. The Oeynhausen shaft reached to the 6th level at a depth of 463 meters, the weather shaft reached to the 2nd level at a depth of 152 meters. In 1924 the briquette factory was put back into operation. On July 1, 1927, the promotion to Caroline was stopped, the cable trip, the promotion and the day-to-day operation took place via the Prince of Prussia location. The coking plant was closed on March 26, 1926. In September 1927 the briquette factory was shut down again. In 1929 the breakthrough took place with the Gustav Heinrich colliery and on July 1 of the same year the Caroline colliery consolidated into the Robert Müser colliery.

Promotion and workforce

Fatty coal was mined at the colliery. The first funding and workforce figures come from the year 1872, around 49,000 tons of hard coal were mined with 260 miners . In 1875, 460 miners extracted 109,340 tons of hard coal. In 1880, 304 miners extracted 118,264 tons. In 1885 the production and workforce increased again, with 624 miners, 149,990 tons were extracted. In 1900 another increase, with 819 employees, 153,503 tons of hard coal were mined. In 1905, 923 miners extracted 167,491 tons. In 1910, 956 miners extracted 220,774 tons. In 1913 the numbers rose again, with 1036 miners more than 254,000 tons of hard coal were mined. In 1915, both the workforce and production fell, with 705 miners producing 178,801 tons. In 1920 the workforce increased to 1,055 miners, 193,909 tons were mined. The mine had the highest workforce with 1536 miners in 1925. In that year 376,118 tons were extracted. In 1926, 1394 miners extracted 418,394 tons of hard coal, the highest extraction in the entire history of the mine. The last figures come from 1928, with 953 employees 282,827 tons of hard coal were mined. In 1872, a connecting railway to the Bochum - Dortmund line of the Bergisch-Märkische Eisenbahn-Gesellschaft (BME), which runs past the Bergisch-Märkische Eisenbahn-Gesellschaft (BME), was put into operation for the dispatch of the extracted coal . The connection to the north past Bochum-North - Dortmund-South line of the Rheinische Eisenbahn-Gesellschaft (RhE) was established with its completion on November 19, 1874.

Search for clues

The mines of the Caroline colliery have completely disappeared, as the area of ​​the former colliery is now part of the Kornharpen central garbage dump (the operating buildings are located on Kornharpener Strasse, roughly where the surface facilities once stood). Only the Karolinenbach reminds of the location of the mine.
