Gezähe
In German-speaking countries, the miner's toolset is known as a ''Gezähe'' (derived from ''gizouuun'', zu ''zawen'', ''gezawen'' – to be usable, advantageous at www.uni-heidelberg.de. Accessed on 19 Aug 2012.) formerly also abbreviated to ''Gezäh''. It is a set of personally-owned mining tools and equipment needed by the in his daily work. In coal mining in central Europe during the 19th and 20th centuries, every miner had his own set of tools. So that they could not be stolen, before the end of his shift they were either locked in a tool chest (''Gezähekiste'') or threaded onto a tool ring (''Gezähering'') which was then locked. To that end, all tools had a hole or eyelet. Tools that were not part of a miner's personal equipment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schlägel Und Eisen
The hammer and pick, rarely referred to as hammer and chisel, is a symbol of mining, often used in heraldry. It can indicate mining, mines (especially on maps or in cartography), or miners, and is also borne as a charge in the coats of arms of mining towns. The symbol represents the traditional tools of the miner, a hammer and a chisel on a handle, similar to a pickaxe, but with one blunt end. They are pictured in the way a right-handed worker would lay them down: the pick with the point to the right and the handle to the lower left, the hammer with the handle to the lower right and the head to the upper left. The handle of the pick protrudes over the head, because the head is not permanently fixed, but can be swapped for a newly sharpened head when it is blunt from use. In coats of arms the symbol is often shown in black ( Johanngeorgenstadt, Hövels), but also in natural colours ( Telnice) or in gold or silver (Abertamy, Bodenwöhr, Gelsenkirchen). __NOTOC__ Examples F ...

Lignite
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials may be present in lignite which are left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is brow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miner's Habit
A miner's habit (german: Berghabit or ''Bergmannshabit'') is the traditional dress of miners in Europe. The actual form varies depending on the region, the actual mining function, and whether it is used for work or for ceremonial occasions. Elements At work, the miner of the Middle Ages in Europe wore the normal costume for his local region – pit trousers (''Grubenhose''), shoes and miner's jacket (''Bergkittel''). Only gradually was the typical miner's uniform created by the addition of unmistakable elements of miner's apparel such as the miner's apron (''Arschleder''), knee pads (''Kniebügel''), miner's cap (''Fahrhaube'' or ''Fahrkappe'', later pit hat (''Schachthut''), the mining tools needed for work in the pit, such as hammers (''Fäustel''), chisels (''Eisen''), wedges, picks (''Keilhauen''), hoes (''Kratze''), shovels, crowbars, pikes (''Brechstangen'') or miner's chisels (''Bergeisen''), mallets (''Schlägel'') or carpenter's hatchets, the miners' safety lamps ...

Krupka
Krupka (; german: Graupen) is a town in Teplice District in the Ústí nad Labem Region of the Czech Republic. It has about 12,000 inhabitants. The town is located in the Ore Mountain Mining Region, an UNESCO World Heritage Site, and during the late Middle Ages it was one of the world-leading producers of tin and silver. The centre of Krupka is well preserved and is protected by law as an urban monument zone. Administrative parts Town parts and villages of Bohosudov, Fojtovice, Horní Krupka, Maršov, Nové Modlany, Soběchleby, Unčín and Vrchoslav are administrative parts of Krupka. Etymology The name "Krupka" was derived from an Old-Czech word ''krupý'', which approximately means "large". Geography Krupka is located about north of Teplice and east of Ústí nad Labem. The southern part of the municipal territory with the built-up area lies the Most Basin, the northern part lies in the Ore Mountains. On the southern border of Krupka there is the Kateřina Reservoir, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seiffen
The town of Seiffen is located in the district of Erzgebirgskreis, which is in the central south of the Free State of Saxony in Germany. The earliest record of the town dates to 1324 when it was referred to as "Cynsifen". Seiffen nestles in the heart of the Ore Mountains (German: ''Erzgebirge''), which are famous for many Christmas traditions. As the silver and tin deposits declined, former miners had to look for new ways to feed their families. In addition to lace making and weaving, the local population turned to wood carving. Nutcrackers, "smoking men", Christmas pyramids (carousels with figures of the Christmas story or from mining) and ''Schwibbögen'' (wooden candle arches, displayed in windows, symbolising the opening of a mine) are some of many Christmas goods made in the Ore Mountains. Seiffen is a centre of the wooden toy industry. History The history of Seiffen started when miners opened up the district 700 years ago. With the recession of ore mining in the area, ...

Hushing
Hushing is an ancient and historic mining method using a flood or torrent of water to reveal mineral veins. The method was applied in several ways, both in prospecting for ores, and for their exploitation. Mineral veins are often hidden below soil and sub-soil, which must be stripped away to discover the ore veins. A flood of water is very effective in moving soil as well as working the ore deposits when combined with other methods such as fire-setting. Hushing was used during the formation and expansion of the Roman Empire from the 1st century BC on to the end of the empire. It was also widely used later, and apparently survived until modern times where the cost of explosives was prohibitive. It was widely used in the United States, where it was known as "booming". A variant known as hydraulic mining where jets or streams of water are used to break down deposits, especially of alluvial gold and alluvial tin, is commonly used. History The method is well described by Pliny t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cassiterite
Cassiterite is a tin oxide mineral, SnO2. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite was the chief tin ore throughout ancient history and remains the most important source of tin today. Occurrence Most sources of cassiterite today are found in alluvial or placer deposits containing the weathering-resistant grains. The best sources of primary cassiterite are found in the tin mines of Bolivia, where it is found in crystallised hydrothermal veins. Rwanda has a nascent cassiterite mining industry. Fighting over cassiterite deposits (particularly in Walikale) is a major cause of the conflict waged in eastern parts of the Democratic Republic of the Congo. This has led to cassiterite being considered a conflict mineral. Cassiterite is a widespread minor constituent of igneous rocks. The Bolivian veins and the 4500 year old workings of Cornwall and Devon, England, are concentrated in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoring
Shoring is the process of temporarily supporting a building, vessel, structure, or trench with shores (props) when in danger of collapse or during repairs or alterations. ''Shoring'' comes from ''shore'', a timber or metal prop. Shoring may be vertical, angled, or horizontal. Methods Buildings Raking shores In this method, inclined members called rakers are used to give temporary lateral support to an unsafe wall. One or more timbers slope between the face of the structure to be supported and the ground. The most effective support is given if the raker meets the wall at an angle of 60 to 70 degrees. A wall-plate is typically used to increase the area of support. Foundations Shoring is commonly used when installing the foundation of a building. A shoring system such as piles and lagging or shotcrete will support the surrounding loads until the underground levels of the building are constructed. Commonly used shoring equipment includes post shores, shoring beams, and timber jacks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mattock
A mattock is a hand tool used for digging, prying, and chopping. Similar to the pickaxe, it has a long handle and a stout head which combines either a vertical axe blade with a horizontal adze (cutter mattock), or a pick and an adze (pick mattock). A cutter mattock is similar to a Pulaski used in fighting fires. It is also commonly known in North America as a "grub axe". Description A mattock has a shaft, typically made of wood, which is long. The head consists of two ends, opposite each other and separated by a central eye. A mattock head typically weighs . The form of the head determines the kind and uses of the mattock: * A ''cutter mattock'' combines the functions of an axe and adze, with its axe blade oriented vertically and longer adze horizontally. * A ''pick mattock'' combines the function of a pick and adze, with a pointed end opposite an adze blade. Both are used for grubbing in hard soils and rocky terrain, with the pick mattock having the advantage of a superio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miner
A miner is a person who extracts ore, coal, chalk, clay, or other minerals from the earth through mining. There are two senses in which the term is used. In its narrowest sense, a miner is someone who works at the rock face; cutting, blasting, or otherwise working and removing the rock. In a broader sense, a "miner" is anyone working within a mine, not just a worker at the rock face. Mining is one of the most dangerous trades in the world. In some countries, miners lack social guarantees and in case of injury may be left to cope without assistance. In regions with a long mining tradition, many communities have developed cultural traditions and aspects specific to the various regions, in the forms of particular equipment, symbolism, music, and the like. Roles Different functions of the individual miner. Many of the roles are specific to a type of mining, such as coal mining. Roles considered to be "miners" in the narrower sense have included: *Hewer (also known as "cake" or "pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
