iron ore was mined at the St. Anna shaft from 1958 to 1974.A chronological overview The shaft was sunk to a depth of 115 metres and was then driven underground to the ore fields of the ‘St. Georg’, ‘Schützenheim’ and ‘Galgenberg’ sections. The headframe and six buildings were built above ground during this period. On […]
the shaft hall was a distribution for ore, material, equipment and miners.A lot of space required in the shaft hall The shaft hall was 56 metres long, 12.50 metres wide and 10 metres high. The steel skeleton structure enclosed the lower third of the headframe. The balustrades of the outer walls were designed with visible […]
the electric hoisting machine raised and lowered the pit cages.Electric floor conveyer machine Directly in front of your location, five metres away, stood the wall of the machine house. Behind it, in the room separated from the rest of the shaft hall, was the hoisting machine. The hoisting machine used here was a ‘floor conveyor […]
winding tower with two pit cages.Innovative conveyor framework for support frame and container requirements. Two counter-rotating conveyor frames with ore bins integrated at the top, travelled up and down in this steel framework construction. Each of these conveyor frames was approx. 1.10 metres wide, 2.80 metres deep and over 10 metres high. They were suspended […]
compressed air was the most important energy source underground.Compressed air as an economical and proven energy source The outer wall of the compressor house stood six metres to the right of your location. Due to their high noise and heat development, only the compressors were housed here. Using the technology available at the time, compressed […]
this is how Sulzbach’s ore was mined.The sketch of the underground routes, tunnels and shafts (black and white) in the background is not to scale and is simplified. The inserted illustration (blue) shows the actual construction of the winding shaft, head frame with pit cages and the St. Anna shaft hall. Plan source (background, B/W): […]
the main haulage shaft from 1962 for all Sulzbach mines.Construction of twelve additional buildings As the main winding shaft, the St. Anna shaft had to be able to fulfil a wide variety of additional functions -especially as all the approximately 450 miners now had to enter and leave from here, they were then divided into […]
the St. Anna shaft went into operation as an additional winding shaft in 1958.Ore extraction from the three neighbouring field sections After the completion of all six operational buildings, which were essential for mining operations, as well as the cable railway, ore mining began The shaft area stretched over 65 x 150 metres and covered […]
the St. Anna shaft was „sunk“.Difficult geological conditions The actual shaft is circular and leads into the depths in the centre below the headframe. Its size and position are marked by the ‘object frame’. The geological conditions here are problematic, because down to a depth of approx. 80 metres, the soil structure consists of non-load-bearing […]
a new overhead cableway supplied the expanding steelworks.2,500 tonnes of ore per day The reliable aerial cableway was chosen as the means of transport for this daily quantity of ore. Since the construction of the first cable railway in 1881 from the Etzmannsberg shaft to the Maxhütte, the company had had good experience with this […]
