Schneekragen
A schneekragen (German for ''snow collar'') or schneehals (''snow neck'') was a safety corridor characteristic for alpine mining. Covered with lumbers or roundwood, it guaranteed somewhat avalanche-safe access to the adits during winter. Furthermore it protected the miners from cornices and ensured the passage of deep snow areas. Miners' houses, workshops and processing plants were often connected through a system of schneekragens with the adits, so the miners did not have to shovel. The corridors, often built of dry stone, barely reached man-high and had to be crossed cowered down or crawling. Because the entries were sometimes covered by cornices some schneekragens kept impassable and dynamite chests like other heavy equipment normally transported with horses had to be dragged through the danger zone.{{Cite web, url=http://www.knappenmusik-gastein.at/heiteres.html, title=Erinnerungen von Josef Frohnwieser als Knappe am Rathausberg, publisher=Knappenmusikkapelle Radhausberg (first ...

Gold Mining
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South. Like all mining, human rights and environmental issues are common issues in the gold mining industry. In smaller mines with less regulation, health and safety risks are much higher. History The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 700 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stubai Alps
The Stubai Alps (in German ''Stubaier Alpen'') is a mountain range in the Central Eastern Alps of Europe. It derives its name from the Stubaital valley to its east and is located southwest of Innsbruck, Austria. Several peaks form the border between Austria and Italy. The range is bounded by the Inn River valley to the north; the Sill River valley (''Wipptal'') and the Brenner Pass to the east (separating it from the Zillertal Alps); the Ötztal and Timmelsjoch to the west (separating it from the Ötztal Alps), and to the south by tributaries of the Passer River and Eisack. Geography Important parts of the Stubai Alps show signs of glaciation. The northern part around the Sellrain valley and the Kühtai is now only lightly glaciated and a popular ski touring destination ( Zischgeles, Lampsenspitze, Pirchkogel, Sulzkogel). The High Stubai around the upper Stubai valley is still heavily glaciated and a classic high mountain touring region in the Eastern Alps. Here there is a glacie ...

Goldberg Group
The Goldberg Group is a sub-group of the Hohe Tauern mountain range within the Central Eastern Alps. It is located in Austria, in the states of Salzburg and Carinthia. Its highest peak is the Hocharn, . Other well known summits are the Hoher Sonnblick, with its observatory at , and the Schareck at Name The name of the group is related to the rich mineral ores of the area and the associated historic mining. Gold was mined in the Rauris valley as well as in the Gastein valley (in the Radhausberg Massif), and helped those two valleys – and also the Archbishops of Salzburg as feudal lords – in the High Middle Ages to gain enormous wealth. Not until the 19th century the mines were finally closed due to unprofitability. Even today, gold can be panned in the Rauris. Peaks like the Goldbergspitze (3,073 m) and Goldzechkopf (3,042 m) recall times long past when gold was mined in the High Tauern. In addition, silver – as indicated by Silberpfennig (2,600 m) – and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Silver Mining
Silver mining is the extraction of silver from minerals, starting with mining. Because silver is often found in intimate combination with other metals, its extraction requires elaborate technologies. In 2008, ca.25,900 metric tons were consumed worldwide, most of which came from mining. Silver sources Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. Specific minerals include argentite (Ag2 S), chlorargyrite ("horn silver," Ag Cl), polybasite (Ag, Cu)16Sb2S11), and proustite (Ag3AsS3). Silver mainly occurs as a contaminant in chalcopyrite and galena, important ores of copper and lead, respectively.Kassianidou, V. 2003. Early Extraction of Silver from Complex Polymetallic Ores, in Craddock, P.T. and Lang, J (eds) Mining and Metal production through the Ages. London, British Museum Press: 198–206 Some ores are actually mined explicitly for their silver value vs the silver being a byproduct of other metals. However ...

Dynamite
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay), and Stabilizer (chemistry), stabilizers. It was invented by the Swedish people, Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany, and patented in 1867. It rapidly gained wide-scale use as a more robust alternative to gun powder, black powder. History Dynamite was invented by Swedish chemist Alfred Nobel in the 1860s and was the first safely manageable explosive stronger than black powder. Alfred Nobel's father, Immanuel Nobel, was an industrialist, engineer, and inventor. He built bridges and buildings in Stockholm and founded Sweden's first rubber factory. His construction work inspired him to research new methods of blasting rock that were more effective than black powder. After some bad business deals in Sweden, in 1838 Immanuel moved Nobel family, his family to Saint Petersburg, where Alfred and his brothers were educated privately under Swedish and Russi ...
