The persistence shaft was a coal mine of the Hänichen coal mining association . The shaft was in the eastern part of the hard coal deposit of the Döhlen basin on Rippiener Flur.
history
The Hänichener Steinkohlenbauverein began to sink the shaft in 1850 . The shaft, set at 309.40 m above sea level, reached a depth of 470 meters. In 1854, the first seam was intersected with a thickness of 2.00 meters at 344 meters. The depth was set at 370 meters. The shaft had a solid, brick-built hothouse in the style of a Malakoff tower , but with a completely unadorned facade. A steam engine with an output of 130 hp was used for the promotion . The steam engine of the dewatering made 36 hp.
On December 1st, 1856, a 940 meter long connecting line to the newly built Hänichener Kohlenzweigbahn was completed. On April 1, 1857, the line, which made it much easier to send the coal, was put into operation.
At a distance of 200 meters to the east, three more coal seams were passed. The 2.60 meters below the 1st seam, 0.30 meters thick, the 2nd seam, 1.50 meters below the 2nd seam, the 0.70 meters thick 3rd seam and 3.70 meters below the 3rd seam 0.50 meter thick 4th seam. While the 2nd seam is only a layer of fire slate, the 3rd seam consists of hard schisty coals and the 4th seam consists of a chert bank.
The mining field of the shaft extended in the southeast to the construction field of the Dresden-Possendorfer Steinkohlenbauverein.
The shaft served as a weather shaft . In 1869 a Guibal centrifugal fan with a diameter of 6 meters was installed here. The fan was driven by a steam engine with an output of 20 hp. In the same year, a processing plant for clear coal was built.
In order to develop the 120 meters lower field to the north of the Rote Ochsen fault , the shaft was sunk further to 470 meters in 15 months from 1886. The sinking was carried out with full production operations. The rock that was encountered was extraordinarily hard, so that when driving the cross passage in hand drilling operations, driving only had to be carried out 62 meters in ten months . Then the work was given to a company from Mülheim an der Ruhr in general items. From February 15, 1889, this worked with compressed air drilling machines and reached the seam after six months and a further 370 meters. The Red Ox fault was traversed over a length of 184 meters and consisted of three jumps. The jumping heights were 48 meters, 30 meters and 42 meters. The seam thickness of initially 2 meters increased towards the northwest to 3.50 meters.
In 1890, the horse-drawn route was started in the area of the Persistence Shaft.
After the dewatering of the Berglust shaft was stopped on June 7, 1905 , the pit water was now lifted over the persistence shaft.
Despite still sufficient coal reserves, operations were stopped in July 1906 and the shaft filled. The 542-m- sole is the deepest bottom of the well and located at -232 NN m.
In the years 1933 to 1939, eight single-family houses were built on the flattened heap. A smoldering fire in the dump caused considerable damage to the buildings between 1942 and 1948. Later measurements of radioactivity showed up to 5740 Becquerel per cubic meter of air in the houses , which was caused by radon penetrating from the dump.
After the filling compound had settled in the shaft tube in 1955 and 1970, the shaft was kept safe in 1973 by the Dresden mountain security service .
