Coal can be mined by both the open cast mining method and the underground mining method. Nigeria''s most exploited coal mines are located at Enugu where NCC operated two underground coal mines and commercial production started in 1916, the peak in coal production was in the late 1950s reaching approximately 920,000 tons per annum.
mine drainage pollution caused by coal mining activity. The mine water is polluted within the sumps in the floor of the long walls. The sumps act as oxidation chambers where groundwater from the fractures is mixed and subsequently reacted with sulphurrich solutes released by coal mining activity.
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.
