Coal breaker Coal breaker A coal breaker is a coal processing plant which breaks coal into various useful sizes. Coal breakers also remove impurities from the coal (typically slate) and deposit them into a culm dump. The coal breaker is a forerunner of the modern coal preparation plant. Generally speaking, a coal tipple was typically used at a bituminous coal mine, where removing impurities was important but sorting by size was only a secondary, minor concern. Coal breakers were always used (with or without a tipple) at anthracite mines. While tipples were used around the world, coal breakers were used primarily in
Coal mining in the United Kingdom at ordinary combustion temperatures (i.e. for the oxidation of carbon - see fossil fuels). The last deep coal mine in the UK closed on 18 December 2015. Twenty-six open cast mines still remain open and Banks Mining said in 2018 they planned to start mining a new site in County Durham. The United Kingdom's onshore coal resources occur in rocks of the Carboniferous age, some of which extend under the North Sea. The carbon content of the bituminous coal present in most of the coalfields is 86% to 88%. Britain's coalfields are associated with Northumberland and Durham, North and South
