Coal mining - Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit ...

Feb 01, 2021  The Alberta government’s decision, in June, to rescind the 1976 coal policy has opened up 420,000 hectares of land classified as Category 2, a designation that had prohibited open-pit coal mining. Much of the area is already covered by coal leases, meaning companies can begin coal exploration and apply to build new open-pit mines.
