The Neuhoffnungsschacht (also: Neue-Hoffnung-Schacht ) was a coal mine of the Baron von Burgker coal and ironworks . The shaft was located in the central part of the hard coal deposit of the Döhlen Basin on Niederhäslicher Flur (parcel “Die Spitze”). The shaft was (together with the neighboring Segen-Gottes-Schacht ) site of the largest firedamp explosion in the Saxon coal mining industry.
history
The Freiherrlich of Burgker coal and iron and steel works began in 1837 on the plateau of wind mountain with the depths of the shaft. The shaft, set at 317 m above sea level, reached a depth of 392.80 meters in 1841 . The first seam found at a depth of 364.80 meters was 4.60 meters thick . The drainage of the mine field took place via a 520-meter-long rose that was excavated from 1839–1842 and reached a depth of 81.75 meters . Their mouth hole , which no longer exists today, was in Burgk at the confluence of Rotkopf-Görg-Strasse and Burgker Strasse. For a while, this rose was used to transfer coal for washing at the Wilhelminenschacht . The daily route Oberes Revier , the mouth of which is located in the garden of Burgk Castle , originally served as a journey for the team . With the shaft, the 3.70 meters below the 1st seam, the 0.90 meters thick 2nd seam, 8.90 meters below the 2nd seam, the 0.70 meters thick 3rd seam and 2.40 meters below the 3rd seam Seam cut through the 0.20 meter thick 4th seam. All 3 seams consist of unworkable fire slate. In 1838 a steam engine with an output of 16 hp, built by the barons of Burgker Steinkohlen- und Eisenhüttenwerke, was built for extraction. A steam engine of the same type was built in 1840 to operate the drainage system.
A hydraulic coal washing facility was set up in 1847 and five beehive ovens for coke production were built in 1854 .
On March 30, 1857, the connection of the shaft to the newly built Hänichen coal branch railway , which made it much easier to transport the coal, was put into operation.
After the sinking of the Segen-Gottes-Schacht in the east, which was completed in 1862, a connection was created between the two shafts. On August 2, 1869, a firedamp explosion occurred in this united mine field, to which almost all miners on the morning shift fell victim. The 276 dead were buried in the Döhlen cemetery and on a specially set up burial place at the Segen-Gottes-Schacht. A monument inaugurated at this location in 1870 commemorates the catastrophe.
With a cross passage directed south-east from the deepest part of the shaft, the seam was approached again at a distance of 180 meters and from here it was possible to realign the seam that plunged further 70 meters to the south-east. In 1871, a Guibal type centrifugal fan with a diameter of nine meters was installed under the suspended bench to improve ventilation of the mine field . In the same year a rescue route with the Windberg shaft of the Potschappler Aktienverein broke through .
In 1886 the hoisting machine of the shaft was implemented as a hoisting machine to the depth of the Marienschacht. In March 1887, the mining in the area of the shaft was stopped. The shaft continued to serve as a weather shaft. The daytime facilities that were no longer needed (laundry and sorting facility) were demolished.
In June 1888, a miner was killed in a firedamp explosion.
In 1898 the daily route was thrown off and its connection to the Burgker Weißeritz tunnel, as well as the connection to the shaft, was dammed to prevent water from entering the Weißeritz during floods. In 1901 the pit ventilator was taken out of service. The Glückauf shaft took on the task of extending the weather shaft . So that the water that is sitting on does not pollute the dewatering of the Blessing God shaft, the shaft was arched watertight at a depth of 136.50 meters and the shaft tube was filled. The shaft water was discharged via the rose.
The total output over the operating period was 1,685,406 tons.
The day facilities were later torn down except for part of the hut house. Part of the shaft site is now used by a saddlery workshop. The hut house is used for residential purposes.
In 1978, the mine was again kept safe by the Dresden mountain rescue service .
