20/01/2019 Following World War I, Germany established a mine warfare research and development command in 1920. Airborne mines were successfully tested in 1931 and acoustic and magnetic mines were developed before the war started. Some 1,500 magnetic mines were available in the spring of 1940, far short of the 50,000 originally ordered. Pressure mines were developed in 1943 but not used

05/05/2020 In more recent times – particularly during the 20 th century – the mines were expanded and the metal ore extracted from within Rammelsberg was a critical part of the expansion of Germany and the war efforts. In all, it’s estimated that about 30 million tonnes of ore were mined from Rammelsberg.
The post-war economic boom in Germany (Wirtschaftswunder) was fuelled by hard coal mined in the states of North Rhine-Westphalia and the Saarland, which powered the industries of West Germany. But hard coal has since lost its competitive edge. As of December 2018, Germany doesn’t have any domestic hard coal mining left.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agri

05/05/2020 Rammelsberg Mines, Goslar, Germany. There’s rattling all around. It’s almost deafening. Hurtling down a tunnel in a small enclosed train, it’s dark. Flashes of light come through the narrow open windows as we race past the occasional artificial lights on the tunnel walls. This is how you descend into the depths of Rammelsberg. Deep underground, it’s cold. It’s much lighter than in ...

The Tagebau Hambach is a large open-pit coal mine (German: Tagebau) in Niederzier and Elsdorf, North Rhine–Westphalia, Germany.It is operated by RWE and used for mining lignite.. The mine is on the site of the ancient Hambach Forest which was purchased by RWE in 1978. They then cut most of it down and cleared it to mine. Only 10% of the forest area remains.

Germany has been the largest lignite producer in the world since the beginning of industrial lignite mining. It still is, followed by China, Russia, and the United States. The softer and moister lignite (also called brown or soft coal) has a lower calorific value than hard coal and can only be mined in opencast operations. When burned, it is more CO2 intensive than hard coal.
The Tagebau Garzweiler is a surface mine (German: Tagebau) in the German state of North-Rhine Westphalia.It is operated by RWE and used for mining lignite. The mine currently has a size of 48 km² and got its name from the village of Garzweiler [] which previously existed at this location. The community was moved to a section of Jüchen with the same name.
Germany - Germany - Resources and power: Germany, which has relatively few domestic natural resources, imports most of its raw materials. It is a major producer of bituminous coal and brown coal (lignite), the principal fields of the latter being west of Cologne, east of Halle, south and southwest of Leipzig, and in Lower Lusatia in Brandenburg.

Mine gas, any of various harmful vapours produced during mining operations. The gases are frequently called damps (German Dampf, “vapour”). Firedamp is a gas that occurs naturally in coal seams. The gas is nearly always methane (CH 4) and is highly inflammable and explosive when present in the air in a proportion of 5 to 14 percent.White damp, or carbon monoxide
Salt Mines. Salt (sodium chloride) is different from other typical mining products, as it is necessary for living, it is an important part of our food. Thus salt is probably the first thing which was mined and it has been a sort of currency for millennia. The first known salt works are about 8,000 years old, found in the Shanxi province of China. Salt lakes and sea water were the

Germany has considerable reserves of lignite, making it one of the country’s most important indigenous sources of energy. There are long-term prospects to mine about 4 billion tonnes of lignite reserves at existing and approved surface mines. The last two hard coal mines were closed in December 2018, following a political decision ten years ...
Germany imports steel from over 130 countries and territories. Industrial Minerals. Mining production in Germany decreased by 10% in March of 2018.

09/03/2016 Germany mined agate in the Nahe River valley which was documented as early as 1497. This brought about the rise of the cutting centre called Idar-Oberstein. Brazil has rich deposits of agate and this was discovered when in the 19th century, the Idar-Oberstein’s cutters exhausted the agate deposits at Nahe and they went on to mine the deposits in Brazil. It lead
