The light hole 21 Deep Weißeritz Tolln was a coal mine of the Royal coal plant Zauckerode . The shaft was located in the western part of the hard coal deposit of the Döhlen basin on Niederhermsdorfer Flur.
history
After the deep Weißeritz tunnel, begun in 1800 , had reached the Niederhermsdorf area, the 21st light hole was dug from 1839. The shaft, which was set at 233.40 m above sea level, reached the first seam with a thickness of 1.50 meters in 1841 at a depth of 72.40 meters and on October 1, 1841 the tunnel bottom . The 0.20 meter thick seam was cut at 77.90 meters and the depth set at 78.54 meters. The deep Weißeritz adit excavated at the level of the 1st seam was driven further west from here. In 1842, after 35.70 meters, the building quality limit of the 1st seam was reached and the drive stopped. In the first quarter of 1844, the Weißeritz tunnel between Neu Leopoldschacht and the 21st light hole was thrown from 310 meters to 10 meters in front of the light hole. Part of the shaft and the filling point were filled. The shaft closed with a wooden platform and covered with mountains.
With the advance of the workings of the Albert shaft to the west of the 1848 geteufte handed Georg shaft for ventilation of the burrows not more. For this reason, the 21st light hole was opened and a 73 meter long fall location was driven up to the level of the Tiefen Elbstolln . The fall site was connected to the Elbe tunnel via a 280 meter long cross passage. In 1865 the shaft and the place where it fell were lined and a weather furnace was installed on the bottom of the Elbe in June 1865 . The first seam in the area of the Elbe tunnel was 3.30 meters thick. The thickness of the 3rd seam passed through here was 0.60 meters. In order to achieve an increase in the volume of the weather, the grate area of the weather furnace was increased three times in 1863.
In 1922, coal mining was stopped in the Albertschacht. The field in the area of the 21st light hole, 1000 meters from the Albertschacht, was not dismantled because the transport of the coal extracted was too complex and the costs too high. The light hole remained open and continued to serve to maintain normal weather flow.
Since the end of the production in the Königin-Carola-Schacht was in sight, one began in February 1935 with the opening of the light hole 21 in order to extract the coal in the estimated order of magnitude of 200,000 t. From a depth of 20 meters, the cross-section was reduced from 2.30 × 1.60 meters to just 1.90 × 1.00 meters. The shaft was torn down and provided with a bolt shot removal. After the Weißeritz adit, which was closed in 1842, was extended to 270 meters from the 21st light hole, an investigation section began to be excavated as far as the Elbe adit in May 1935 when the seam fell. In January 1936 the Elbstolln level was reached. The Elbe tunnel was cleared and driven 600 meters further west. From the Weißeritz tunnel a 636 meter long chain mountain was driven up to the 3rd main section at 46.7 m above sea level. Between the 3rd and ½ 4th main line, as well as between the ½ 4th and the lowest point at −13.8 m above sea level, 2 further piles of production were excavated. In 1938 the blind shaft hoisting machine of the Königin-Carola-Schacht was set up on the light hole and the production started with a two-tier hoisting frame. From May 1943 a battery locomotive was used for transport on the 2nd main line. It was the first battery locomotive in the Döhlen district. It was supplied by Siemens & Schuckert .
After the end of the Second World War, mining operations continued seamlessly. The systems were not dismantled. The greatest obstacle was the lack of labor. These were attracted by high food rations, special allotments and allowances for alcohol, cigarettes and coals. Even before the liquidation of the Sächsische Werke Aktiengesellschaft on March 11, 1947, the factory was subordinated to the coal industry I Steinkohle as the Freital coal plant from June 1, 1946.
At the end of 1948, the stocks below the Elbe valley were exhausted. After the remaining stocks between the Elbe adit and the Weißeritz adit had been dismantled, the last 832 t were produced in January 1952. Coal was mined and operations ceased on January 28, 1952. With the mining of coal to the absolute limit of construction worthiness, this part of the field grew to around 900,000 t between 1935 and 1952. Coal mined. The shaft was thrown out and the shaft was filled. The battery locomotive was moved to the Oppelschacht and was used there on the fifth main line.
