Mining In The Harz
Mining in the Upper Harz region of central Germany was a major industry for several centuries, especially for the production of silver, lead, copper, and, latterly, zinc as well. Great wealth was accumulated from the mining of silver from the 16th to the 19th centuries, as well as from important technical inventions. The centre of the mining industry was the group of seven Upper Harz mining towns of Clausthal-Zellerfeld, Clausthal, Zellerfeld, Sankt Andreasberg, Wildemann, Bad Grund, Grund, Lautenthal und Altenau, Lower Saxony, Altenau. History The Upper Harz was once one of the most important mining regions in Germany. The major products of its mines were silver, copper, lead, iron and, from the 19th century, zinc as well. The main source of income, however, was silver. From the 16th to the middle of the 19th centuries about 40–50% of the entire German silver production originated in the Upper Harz. The taxes raised from this contributed significantly to the revenue of the ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walkenried Abbey
Walkenried Abbey () was a Cistercians, Cistercian abbey located in the village of Walkenried in Lower Saxony, Germany. Founded in 1127 on the southern rim of the Harz mountain range, the remnants of the monastic complex since 2010 are part of the Upper Harz Water Regale World Heritage Site. History The third Cistercian monastery on Kingdom of Germany, German territory was founded by Adelheid of Lare (Großlohra, Lohra), wife of Count Volkmar of Klettenberg, under the first abbot Henry I (1127–28); the foundation was backed by King Lothair II, Holy Roman Emperor, Lothair III and confirmed in 1137 by Pope Innocent II. The constituent convent arrived in 1129 from Kamp Abbey in the Rhineland, where Adelheid had stayed on a pilgrimage. The premises were conveniently situated on the Wieda (river), Wieda creek and the southern slopes of the Harz mountains. Shortly afterwards construction work of a Romanesque architecture, Romanesque basilica began, which was Dedication of churches, dedi ...

Kingdom Of Prussia
The Kingdom of Prussia (, ) was a German state that existed from 1701 to 1918.Marriott, J. A. R., and Charles Grant Robertson. ''The Evolution of Prussia, the Making of an Empire''. Rev. ed. Oxford: Clarendon Press, 1946. It played a significant role in the unification of Germany in 1871 and was a major constituent of the German Empire until its German Revolution of 1918–1919, dissolution in 1918. Although it took its name from the Prussia (region), region called Prussia, it was based in the Margraviate of Brandenburg. Its capital was Berlin.

The Kingdom of Hanover () was established in October 1814 by the Congress of Vienna, with the restoration of George III to his Hanoverian territories after the Napoleonic Wars, Napoleonic era. It succeeded the former Electorate of Hanover, and joined 38 other sovereign states in the German Confederation in June 1815. The kingdom was ruled by the House of Hanover, a cadet branch of the House of Welf, in Personal union of Great Britain and Hanover, personal union with Great Britain between 1714 and 1837. Since its monarch resided in London, a viceroy, usually a younger member of the British royal family, handled the administration of the Kingdom of Hanover. The personal union with the United Kingdom ended in 1837 upon the accession of Queen Victoria because semi-Salic law prevented females from inheriting the Hanoverian throne while a dynastic male was still alive. Her uncle Ernest Augustus, King of Hanover, Ernest Augustus thus became the ruler of Hanover. His only son succeeded h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coking Coal
Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude petroleum in petroleum refineries. Coke may also be formed naturally by geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116. It is the residue of a destructive distillation process. Production Industrial coke furnaces The industrial production of coke from coal is called coking. The coal is baked in an airless kiln, a "coke furnace" o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Blasting
Drilling and blasting is the controlled use of explosives and other methods, such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut. Drilling and blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocity explosives are used for relatively hard rock in order to shatter and break the rock, while low velocity explosives are used in soft rocks to generate more gas pressure and a greater heaving effect. For instance, an early 20th-century blasting manual compared the effects of black powder to that of a wedge, and dynamite to that of a hammer. The most commonly used explosives in mining today are ANFO based blends due to lower cost than dynamite. Before the advent of tunnel boring machines (TBMs), drilling and b ...

Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, charcoal (which is mostly carbon), and potassium nitrate, potassium nitrate (saltpeter). The sulfur and charcoal act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building Pipeline transport, pipelines, tunnels, and road#Construction, roads. Gunpowder is classified as a Explosive#Low, low explosive because of its relatively slow decomposition rate, low ignition temperature and consequently low brisance, brisance (breaking/shattering). Low explosives deflagration, deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonation, detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Upper Harz Water Regale
The Upper Harz Water Regale (, ) is a system of dams, reservoirs, ditches and other structures, much of which was built from the 16th to 19th centuries to divert and store the water that drove the water wheels of the mines in the Upper Harz region of Germany. The term ''regale'', here, refers to the granting of royal privileges or rights (''droit de régale'') in this case to permit the use of water for mining operations in the Harz mountains of Germany. The Upper Harz Water Regale is one of the largest and most important historic mining water management systems in the world. The facilities developed for the generation of water power have been placed under protection since 1978 as cultural monuments. The majority are still used, albeit nowadays their purpose is primarily to support rural conservation (the preservation of a historic cultural landscape), nature conservation, tourism and swimming. From a water management perspective, several of the reservoirs still play a role in f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
