Notably there was a daily service between Aue and Berlin. Zobes is a small village in the Vogtland mountains. In the late s the company was restructured and Object 90 was split up into several mining division: To transport coal and supply the mining operations in the Erzgebirge Ore Mountains , the line was soon extended along the Mulde and the Schwarzwasser valleys to Schwarzenberg. The most important deposits are described below.
November Learn how and when to remove this template message. The mill processed a total of Despite falling market share in the s, the importance of the route for transport in the western Erzgebirge was undisputed. Mining in Schneeberg continued until reusing many shafts from previous silver and cobalt mining. Mining took place at Bärenhecke, Niederpöbel, Johnsbach and Freiberg. Annaberg-Buchholz in the central Ore Mountains is one of the famous historical silver mining towns of the Ore Mountains.

Uranbergbau im Erzgebirge und Kalter Krieg. Depending on the chemistry of the ore it used both acid and soda-alcalic processes to produce yellowcake. Shaft with a depth of 1, m will stay open although it is flooded and provide a controlled path for radon-bearing air to escape from the mine. Other were taken out of the Wismut GmbH because no restoration was required on these sites; these and formed DFA GmbH, which was subsequently privatised. The following table presents the Wismut resources as of 1 January An unsuccessful attempt was also made to produce base metals, silver and selenium as by-products.
The largest unmined resource was discovered in the late s and early s north of Leipzig , hosted by carboniferous volcano-sedimentary rock units. This deposit was the first of all Wismut deposits to be supplied with large modern mining shafts and powerful ventilation in the mids. Beside the uranium-bearing mineralisation types, there are about one dozen different styles of other mineralisation ranging from Sn-W, Pb-Zn, fluorite-barite to quartz-hematite. It also owns the exploration rights for the tungsten-tin base metal deposit at Pöhla-Globenstein. Erzgebirge and Vogtland were the first exploration targets for uranium and host the largest number of deposits mined by Wismut.
There are two ore horizons containing disseminated pitchblende and coffinite. It is located in the exocontact of the Eibenstock granite underlying the deposit. The deposit is connected by a several kilometer long adit to the Elbe River in Dresden. After the political changes production slowed down in and eventually stopped on 31 December
The most important deposits are described below. It was decided to explore these deposits underground using an adit, which was started in Schneeberg at the southern end of the deposit became Object 03 and Oberschlema Object Most likely it is a combination of a sedimentary style and hydrothermal mineralisation. It was the last Saxonian hard coal mine to be shut down.

Uranium mining by SAG Wismut started in and ended in , producing about tonnes of uranium. Restoration of the area after was carried out by the Königstein division of Wismut GmbH. Articles needing additional references from November All articles needing additional references Articles containing German-language text Articles containing Czech-language text. The ore mined was transported by a cable way down to the Elbe river valley from where it was transported by rail to the mill at Seelingstädt. Object 09 was established to mine the Niederschlema-Alberoda part of the ore field. The total resource of the deposit is about , tonnes of uranium mined and unmined reserves as well as inferred and speculative resources.
The small uranium deposit Bergen was mined only few kilometers away and was connected underground to the Zobes mines. Mining for hard coal in the area is known to date from the 16th century. The company also operated sand pits, both for its construction needs but mostly to get material to refill stopes at Ronneburg. These fires became such a major problem that whole parts of the underground area had to be sealed off and production was heavily impacted.
The source for the uranium was most likely local volcanic rock units. After production ceased, the area was recultivated, including flooding the mine, removing the mine buildings and covering the waste rock area. This major geological structure with a length of several hundred kilometres strikes NW-SE, running from the central Bohemian Massif in the Czech Republic to central Germany. In the s, there was a fast train service with through coaches from Berlin to Cranzahl on the line.
Uranium mineralisation occurs in irregular shaped bodies of highly variable size and uranium content in average 70 tonnes of uranium per body. This article has multiple issues. Significant resources were discovered and mining started in However, there were many difficulties with mining of the deposit because that particular style of mineralisation was unknown to the East German and Soviet mining experts. Most deposits are situated in the western Ore Mountains and the neighbouring Vogtland region, whereas the central and eastern Ore Mountains contain only a few smaller deposits.
Because of the mining of uranium under the line by the Soviet Wismut company, the branch line closed about for safety reasons. Like Hämmerlein, Tellerhäuser also showed a significant tin mineralisation in skarns as well as magnetite. The size of the mineralisations ranges from very small deposits with some hundred kilogrammes of uranium content and a few mineralised veins, up to the giant deposit of Schneeberg-Schlema-Alberoda containing nearly , tonnes of uranium and about 2, mineralised veins.
The ore field contains about 1, mineralised veins. Tin mining ceased in and barite mining in After the coal was milled at Crossen. This article has multiple issues.
Veins of this type contain dolomite, calcite, pitchblende, minor sulphides and selenides especially clausthalite. This led to many problems in the first decade of mining. Uranium exploration and mining concentrated in the first years after World War II on the old mining areas of the Ore Mountains and adjacent Vogtland mountains. Significant resources were discovered and mining started in After the Second World War, Soviet scientists started exploring the old mining areas for uranium, and mining commenced in even before SAG Wismut was established in The low safety and technology standards meant significant health risks for the miners.

In the late s the company was restructured and Object 90 was split up into several mining division: Mining started in and it developed into one of the main producers of SDAG Wismut in the s, with more than 1, tonnes of uranium per year in this decade. After uranium resources were depleted the mine was transferred to another mining company that started mining barite on a fault zone parallel to the uranium veins.
