The German Continental Deep Drilling Programme (German: Kontinentales Tiefbohrprogramm der Bundesrepublik Deutschland, lit. 'Continental deep-drilling program of the Federal Republic of Germany'), abbreviated as the KTB borehole, was a scientific drilling project carried out from 1987 to 1995 near Windischeschenbach, Bavaria.
The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
The German word Talsperre (literally: valley barrier) may mean dam, but it is often used to include the associated reservoir as well. [1] The reservoirs are often separately given names ending in -see, -teich or -speicher which are the German words for "lake", "pond" and "reservoir", but in this case all may also be translated as "reservoir".
The field was discovered in 1981 through the Mittelplate 1 well, which confirmed that the reservoir contained 75 million tonnes (83,000,000 tons) of crude oil. As early as the 1950s, geologists suspected the presence of oil off the German coast. Preliminary test drilling in the 1960s did indeed turn up indications of oil, though not in ...
It is said that in 1903 on the Namedy peninsula, a 343 m deep borehole was drilled into a CO 2-containing aquifer to extract carbon dioxide for mineral water.The reason for boring the hole at this location was that CO 2 gas bubbles were seen rising in the waters of the old Rhine oxbow lake.
Hambach is the largest open-pit mine in Germany, with an area of 3,389 hectares (as of 2007), with an approved maximum size of 8,500 hectares. About forty million tons of lignite are produced annually in this mine. It has recently [when?] been estimated that 1,772 million tons of lignite are still available for mining.
The Federal Maritime and Hydrographic Agency of Germany (German: Bundesamt für Seeschifffahrt und Hydrographie, BSH) is a German federal authority based in Hamburg and Rostock. With some 800 employees, the agency's tasks include maritime safety , hydrographic survey, maritime pollution monitoring, and approvals of offshore installations.
The A 44 and A 61 motorways that crossed the planned mine area were affected as well. The A 44 was closed in 2005, dismantled in 2006 and traffic rerouted to the widened A 61 and A 46 motorways. In 2017, as the mine expanded to the west, the A 61 was closed with traffic diverted onto a stretch of newly built A 44n to the east of its original route.
