Coal

Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface the 1960s to early 1970s. However, activities in this sector began to nose-dive considerably by the mid-1970s due to a number of political and economic factors, especially the the total contribution of the Mining sector (i.e., coal mining, metal ores and quarrying and other minerals) to the 2015 GDP is about 0.15%. 2Nigerian Mining Sector Brief 1 Nigerian Mining Sector Brief
