The Haus Sachsen Schacht was initially a shaft from the Haus Sachsen mine and later from the Neuer St. Joachim mine between Clausthal-Zellerfeld and Wildemann in the Upper Harz Mountains.

history

The shaft was built from the original pit Ritter St. Georg and was from 1548 sunk .

1551 had been started in the shaft luck Ward tunnel excavate . This water solution tunnel was intended to improve the ventilation of the pits being created at Wildemann and, in particular, to allow the pit water to drain away. A short time later, the work was interrupted and continued in 1568.

From 1721 the shaft was operated by the Neuer St. Joachim mine .

Between 1800 and 1817, the Tiefen-Georg-Stollen was expanded towards Wildemann, which was connected to the shaft at a depth of 143 Lachtern (275 meters). The section to the Johanneser Schacht had a length of 304 Lachtern (585 meters) and up to the Charlotter Schacht 162 Lachter (312 meters).

Subsequently, in the course of an operational restriction, the operation of the New St. Joachim mine was stopped in 1817. Up to this point in time, the Sachsen Schacht building had been sunk 34 Lachter (65 meters) below the bottom of the Tiefen-Georg-Stollen seiger .

In 1819, the Adolf tunnel , a side tunnel of the 19-Lachter tunnel , was cut through with the Sachsen Schacht house. It was used as a conveyor tunnel to transport mined ore to the stamping mills above Wildemann. For this purpose, a railroad was created, which made it possible to cover the 750 Lachter (1443 meters) long route within 8 minutes with an English car . This car was operated by a man who operated the brake in an emergency. One car held 11 ctr. (roughly 550 kg) and was moved 16 times between the Sachs Schacht house and the mouth of the 19 Lachter tunnel during an 8-hour shift. The pitch per laugh was approximately 1.3 inches (roughly 1.6 cm per meter).

In the course of the excavation of the Ernst-August-Adit , the Haus Sachsen shaft had to be repaired and lowered by a further 25 peaks (48 meters). This resulted in a difference in height of 59 Lachtern (114 meters) between the Tiefen-Georg-tunnel and Ernst-August-tunnel in the shaft. At this point in time (1849), the Sachsen Schacht house had a sweeper wheel above ground and an artificial wheel underground, which had been installed after 1805 and was installed between the 19-Lacher tunnel and the 13- Lacher tunnel .

In 1853 the shaft had reached its final depth of 189 pools (around 360 meters). The shaft was connected to the Ernst August tunnel by a 13 Lachter (25 meters) long cross passage. In June 1864 the last breakthrough of the Ernst-August-tunnel between the house of Sachsen Schacht and the blind shaft Ernst-August took place . This section of tunnel between the two shafts had a length of 445 Lachter (856 meters), while it was 859 Lachter (1653 meters) up to the pen shaft of the rainbow pit.

In 1880, the Neuer St. Joachim mine and thus also the Saxon shaft were stopped.

Mined ores

Silver-containing galena ( galena ) were primarily mined. In the process, 33 pounds of lead only 1 lot of silver were won (this meant that almost 1 ton of lead ore was extracted to get 1 kg of silver). This ratio was rather poor compared to other mines in the area.

In addition, chert , barite (barite), anglesite (vitriol lead ore) and cerussite (white lead ore), malachite , quartz and fine-grained greywacke were mined.

costs

In 1849, 11,474 Reichstaler were planned for the repair of the shaft and the subsequent lowering from the level of the Tiefen-Georg-Adit to the new Ernst-August-Adit .

Johannes Kurhaus

In 1893, the Johanneser Kurhaus was built by Wilhelm Gregs in the area of ​​the colliery house. The mine house was demolished in 1897. The elegant Kurhaus was used as a hospital in 1917 during the First World War and in 1920 the Gregs family sold it to the charity for the tobacco industry for leasing. The further development of the Kurhaus has to be researched. Finally it was demolished in 1969. Since 1991 the area has been part of the Johanneser Bergwiesen nature reserve .
