Döhlen weather shaft
The Döhlener weather shaft was a weather shaft in the coal field of the Döhlen basin in the area of the city of Freital in Saxony . It was used to ventilate the mine field on the left of the Weißeritz , which belonged to the Zauckerode Royal Coal Works .
history
With the expansion of the mine workings of the Royal Coal Works in the direction of the Weißeritz, a dangerous weather situation arose for the first time in 1855/56 when the III. Main route was no longer passable after strong carbon dioxide emissions . When the second main line was driven to the border of the mine field with the Burgker works , methane gas leaks increased . This weather situation was no longer manageable with the existing weather oven on the Ernst route . As a provisional solution, two weather sets were first installed in the Döhlen art shaft in the filling point of the fourth main line, which were driven by the art rod there. These went into operation on June 12, 1558.
In order to fundamentally solve the problem of mine ventilation, the Royal Works dug a weather shaft between the field rods of the Döhlen art shaft in 1858. The shaft set at 164.20 meters above sea level was brought down to the second main section at 84.00 m. The 4.0 m thick first seam was cut from around 40 meters . On April 27, 1858, a rising weather section on the V main line at a depth of 164.4 m was brought to a breakthrough at the shaft. The two weather sets installed in the shaft consisted of four fixed cast iron boxes, in which pistons covered with sheet iron each performed a stroke of a little over a meter. They were driven directly via the field linkage of the Döhlen art shaft. 110 cubic meters of waste could now be pumped out of the pits per minute. The shaft went into operation in the second quarter of 1859. The incoming shaft was the Döhlen art shaft.
In 1873 the original weather sets were canceled. The shaft was lined and equipped with a Guibal fan with a diameter of seven meters and a width of 1.80 meters. Driven by a steam engine, it now had an output of 600 cubic meters of air per minute.
On 30./31. July 1897, after extreme rainfall in the catchment area of the Weißeritz, one of the most severe floods to date occurred. The pit area was flooded 0.60 meters high. The water penetrated into the boiler house and machine house and put the shaft out of service on the evening of July 30th. The weather stretches leading to the shaft were completely destroyed by the water that penetrated through the Ernst stretch and then abandoned. With that the shaft had lost its function. The Mehnerschacht in reserve then took over its task .
In 1908 the shaft was dropped. When the Weißeritz flood on July 6, 1958, the shaft custody collapsed. The shaft tube was later filled with goods from surrounding department stores that were damaged by the flood. A rescue station of the German Red Cross is now located in the remaining shaft buildings .
In 1985, the mine was subsequently kept by the Dresden mountain rescue service .
