Mining In England
Mining in the United Kingdom produces a wide variety of fossil fuels, metals, and industrial minerals due to its complex geology. In 2013, there were over 2,000 active mines, quarries, and offshore drilling sites on the continental land mass of the United Kingdom producing £34bn of minerals and employing 36,000 people. Brief history The United Kingdom has a rich history of mining. Mining of non-ferrous minerals, particularly of copper and tin, has been ongoing since the Bronze Age. For example, copper was mined in Wales during approximately 2200–850 BC including the Great Orme. Metalworking debris found beneath the ramparts at Beeston Castle in Cheshire is evidence of bronze production during the Bronze Age. Later, lead and copper attracted the Romans to Britain. The Romans introduced iron tools and used local slaves to mine galena, an important lead ore mineral, from which they refined lead, tin and silver. These metals were used locally and also transported by ship throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kellingley Colliery Geograph 001
Kellingley Colliery, known affectionately as ''the 'Big K''', was a deep coal mine in North Yorkshire, England, east of Ferrybridge power station. It was owned and operated by UK Coal. The colliery closed on 18 December 2015, marking the end of deep-pit coal mining in Britain. The site is earmarked for commercial development. History Exploratory boreholes sunk in the 1950s established that there were up to seven workable seams of coal at Kellingley. The sinking of its two shafts started in 1960. Its sandy and porous geology down to about was waterlogged. Boreholes drilled around each shaft position had sub-zero-temperature brine pumped through them to freeze the ground down to about . The sinking personnel had to work in sub-zero temperatures until the shafts were below this frozen ground. The shafts were eventually sunk to a depth of around . After a concrete lining sealed the shafts, the cooling brine was stopped and the frozen ground allowed to thaw. Grout, a thin ce ...
