Mining methods: Underground or 'deep' mining. Coal & Its Uses Electricity Generation; Cement Manufacturer. Steel Making A blast furnace typically uses iron ore, coke.

Coal Mineral Deposits In Nigeria And Its Uses

Method of Coal Mining in Nigeria, and West Africa. During the coal mining era, the method used in the Western part of Africa especially in Nigeria was the underground mining. This process is quite inexpensive when compared to other mining methods, but has its own disadvantages. Some of which include methane explosions, underground water

A new classification method has been developed that uses imaging techniques for the microscopic characterisation of the individual grains present in ground coal samples. The grains are sorted into five grain classes, based on vitrinite abundances. Underground coal mining emits high volumes of methane, diluted in ve Low Emission Coal Use.
