The Moritzschacht was a coal mine of the Gitterseer Steinkohlenbauverein . The shaft was in the northern part of the hard coal deposit of the Döhlen basin on the Gitterseer corridor.
history
The Gitterseer Steinkohlenbauverein began to sink the shaft in 1836 . A steam engine supplied by the MH Göbel company from Zauckerode in 1837 was used for the promotion . In 1838 the Graeflich Einsiedel'sches Eisenwerk zu Lauchhammer supplied a steam engine for dewatering.
The shaft, set at 184.40 m above sea level, reached a depth of 268.30 meters. The Gitterseestolln came in at a depth of 14.80 meters. From 145.25 meters, the first seam with a thickness of 2.70 meters was intersected. The second seam, penetrated at 149.60 meters, consisted of a 0.35 meter thick layer of carbonaceous slate and the third seam, penetrated at 152.00 meters, consisted of fire slate and carbonaceous shale with a thickness of 0.70 meters. When the first seam was reached, the first floor was hit. In order to align the seams falling at 15 ° to the southeast at the shaft, the second level was created at a depth of 179.00 meters and the third level at a depth of 267.00 meters. Opened sole. The II. Level is identical to the I. level of the neighboring Emma shaft . On this level, the 1st seam in the south-east direction at a distance of 110 meters from the shaft and in the III. Bottom found at a distance of 270 meters from the shaft with a thickness of 3.50 meters and a dip of 25 °. In the III. The bottom of the northbound cross passage reached the monzonite basement after 10 meters .
In a south-westerly direction, the mining ended at the first jump of the Red Ox , the main fault in the Döhlen basin. From 1955, VEB Steinkohlenwerk Freital mined parts of the seam that were worth building in the area of the 400 meter wide fault. The construction site of the Potschappler Aktienverein was on the southwest edge of the fault. The seams are about 230 meters higher here.
In the north of the shaft was the construction site of the Coschütz hard coal works. Remaining space was removed here towards the end of operations.
The shaft was connected to the Meisel shaft over several routes . From this shaft from the III. Seam parts located at the bottom of the Moritzschacht dismantled.
In 1856, the shaft was the first conveyor system in the area to be connected to the newly built Hänichen coal branch line . Operations began on April 1, 1857.
After the bankruptcy proceedings against the Gitterseer Steinkohlenbauverein opened on July 21, 1859, remaining areas were mined by the end of December 1859. In the last six months, 93,000 bushels of coal were mined at a sales price of 5.25 groschen per bushel. The cost was 5.65 groschen per bushel of coal extracted.
After the cessation of operations, the shaft was filled and in July 1861 the embankment of the connecting railway was removed. The uphill siding remained. It served to supply the coking plant still in operation on Moritzschacht. Until May 1869, the coal supplied by the Hermannschacht was coked here. When the Hermannschacht was closed, the coking plant was also closed.
In 1992, the shaft was aufgewältigt and the Bergsicherung Dresden to the grid lake Tolln here with a Betonplombe custody .
