Dorothea-Stolln
The Dorothea-Stolln, also known as Himmlisch Heer Fundgrube Dorothea, is a former underground mine in Cunersdorf near of Annaberg-Buchholz in Germany. Today, it is a visitor mine with a length of 53 km and a constant temperature of 8 °C. The Upper Saxon word ''Stolln'' means an adit, the German word ''Fundgrube'' was used to describe the pit that was the first to be awarded on a newly discovered Field (mineral deposit), field. History In the 16th century, mining activities in Cunersdorf started. Due to the high yields, the mine quickly gained popularity. As of 1536, they earned 2409 ''Guldengroschen'' per ''Kux'' (non-material shares of a mine) in 2 and a quarter years. This was mainly due to a high concentration of silver (up to 40 %) in a lode. However, yields fell again in the following years. During the construction of an shaft, the year 1551 was discovered 125 m below the ground. The entrance that is still used today was constructed in 1853. The mining started with silver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Annaberg-Buchholz
Annaberg-Buchholz () is a town in Saxony, Germany. Lying in the Ore Mountains, it is the capital of the district of Erzgebirgskreis. Geography The town is located in the Ore Mountains, at the side of the ''Pöhlberg'' ( above sea level). History The previously heavily forested upper Ore Mountains were settled in the 12th and 13th centuries by Franconian farmers. Frohnau, Geyersdorf, and Kleinrückerswalde—all now part of present-day town—are all attested from 1397. Barbara Uthmann introduced braid- and lace-making in 1561 and it was further developed in the 1590s by Belgian refugees fleeing the policies of Fernando Álvarez de Toledo, 3rd Duke of Alba, Spain's governor over the Low Countries. The industry was further developed in the 19th century, when Annaberg and Buchholz were connected by rail to Chemnitz and each other and both settlements had specialized schools for lace-making. The population of Annaberg in the 1870s was 11,693. This had risen to 16,811 by 1905, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visitor Mine
A mine, i.e. an industrial facility for the underground extraction of mineral commodities, has three operating phases: it may be open or running, or closed or it may be a working museum. Most mines are simply closed once they are no longer productive. For safety they are usually partially destroyed (filled in). However, many mines are at least partially accessible today to visitors. In such cases they may be referred to as show mines or visitor mines if the focus is mainly on visiting the former mine, or mining museums if the mine only forms part of a museum. Most show mines have been set up in abandoned mines. In recent decades, however, they are often established immediately after mining ceases, creating some jobs funded at least partially by cultural tourism. Overview A show mine is often just a small part of a much larger mining facility that is developed, secured and provided with educational exhibits and installations. Such mines are usually equipped with fixed electrical l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Saxon
Upper Saxon (german: Obersächsisch, ; ) is an East Central German language spoken in much of the modern German state of Saxony and in adjacent parts of southeastern Saxony-Anhalt and eastern Thuringia. As of the early 21st century, it's mostly extinct and a new regiolect (also known as ) has emerged instead. Though colloquially called "Saxon" (), it is not to be confused with the Low Saxon dialect group in Northern Germany. Upper Saxon is closely linked to the Thuringian dialect spoken in the adjacent areas to the west. Standard German has been heavily based on Upper Saxon, especially in its lexicon and grammar. This is due to it being used as the basis for early developments in the standardization of German during the early 1500s, including the translation of the Bible by Martin Luther. History Upper Saxon evolved as a new variety in the course of the medieval German '' Ostsiedlung'' (eastern colonisation) from about 1100 onwards. Settlers descending from the stem duchi ...

Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field (mineral Deposit)
A field is a mineral deposit containing a metal or other valuable resources in a cost-competitive concentration. It is usually used in the context of a mineral deposit from which it is convenient to extract its metallic component. The deposits are exploited by mining in the case of solid mineral deposits (such as iron or coal) and extraction wells in case of fluids (such as oil, gas or brines). Description In geology and related fields a deposit is a layer of rock or soil with uniform internal features that distinguish it from adjacent layers. Each layer is generally one of a series of parallel layers which lie one above the other, laid one on the other by natural forces. They may extend for hundreds of thousands of square kilometers of the Earth's surface. The deposits are usually seen as a different color material groups or different structure exposed in cliffs, canyons, caves and river banks. individual agglomerates may vary in thickness from a few millimeters up to a kilomet ...

Guldengroschen
The ''Guldengroschen'' or ''Guldiner'' was a large silver coin originally minted in Tirol in 1486, but which was introduced into the Duchy of Saxony in 1500. The name "''Guldengroschen''" came from the fact that it has an equivalent denomination value in silver relative to that of the '' goldgulden'' (60 ''kreuzer''). In the latter years of the 1470s and early years of the 1480s Sigismund of Austria issued decrees that reformed the poor state of his region's coinage by improving the silver fineness back to a level not seen in centuries (.937 pure) and created denominations larger than the ubiquitous, but fairly low valued ''Groschen'' of 4 to 6 ''Kreuzer'' that were in use. In 1484, small numbers of "half ''guldengroschens''" valued at 30 kreuzer were issued. This was a revolutionary leap in denomination from the smaller pieces, and surpassed even the large '' testones'' of Italy which were the highest weight coins in use. Finally, in 1486 the full sized ''guldengroschen'' of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lode
In geology, a lode is a deposit of metalliferous ore that fills or is embedded in a fissure (or crack) in a rock formation or a vein of ore that is deposited or embedded between layers of rock. The current meaning (ore vein) dates from the 17th century, being an expansion of an earlier sense of a "channel, watercourse" in late Middle English, which in turn is from the 11th-century meaning of ''lode'' as a ‘course, way’. The generally accepted hydrothermal model of lode deposition posits that metals dissolved in hydrothermal solutions (hot spring fluids) deposit the gold or other metallic minerals inside the fissures in the pre-existing rocks. Lode deposits are distinguished primarily from placer deposits, where the ore has been eroded out from its original depositional environment and redeposited by sedimentation. A third process for ore deposition is as an evaporite. A stringer lode is one in which the rock is so permeated by small veinlets that rather than mining the v ...

Leipzig
Leipzig ( , ; Upper Saxon: ) is the most populous city in the German state of Saxony. Leipzig's population of 605,407 inhabitants (1.1 million in the larger urban zone) as of 2021 places the city as Germany's eighth most populous, as well as the second most populous city in the area of the former East Germany after (East) Berlin. Together with Halle (Saale), the city forms the polycentric Leipzig-Halle Conurbation. Between the two cities (in Schkeuditz) lies Leipzig/Halle Airport. Leipzig is located about southwest of Berlin, in the southernmost part of the North German Plain (known as Leipzig Bay), at the confluence of the White Elster River (progression: ) and two of its tributaries: the Pleiße and the Parthe. The name of the city and those of many of its boroughs are of Slavic origin. Leipzig has been a trade city since at least the time of the Holy Roman Empire. The city sits at the intersection of the Via Regia and the Via Imperii, two important medieval trad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wismut (company)
SAG/SDAG Wismut was a uranium mining company in East Germany during the time of the Cold War. It produced a total of 230,400 tonnes of uranium between 1947 and 1990 and made East Germany the fourth largest producer of uranium ore in the world at the time. It was the largest single producer of uranium ore in the entire sphere of control of the USSR. In 1991 after German reunification it was transformed into the Wismut GmbH company, owned by the Federal Republic of Germany, which is now responsible for the restoration and environmental cleanup of the former mining and milling areas. The head office of SDAG Wismut / Wismut GmbH is in Chemnitz-Siegmar. History The Ore Mountains (german: Erzgebirge; cs, Krušné hory) in southern East Germany at the border with the Czech Republic are closely connected to the history of uranium exploitation. The metal was discovered in a sample from a silver mine in the mountain range, and uranium was produced first as a by-product in the early ...
