Like other parts of the world, coal is the oldest commercial fuel, dating in Nigeria from 1916 when 24,000 tons were produced. Production peaked at near one million tons in 1959, before declining to the present insignificant level. This is due to the
The Geology of Nigeria is dominated by three major rock types; the crystalline (igneous and metamorphic rocks) and sedimentary rocks both occurring approximately in equal proportions.
Coal mining in the Enugu area of Nigeria has generated a lot of mine waste that has been dumped in landfills and surface dumps chosen for convenience and proximity to the waste source rather than environmental, geologic or engineering considerations. Environmental degradation and groundwater contamination has resulted. Structural analysis of the area shows that the geological formations are ...
2. Geologic setting. The Benue Trough is an intracontinental Cretaceous sedimentary basin in Nigeria. It has up to 6000 m of Cretaceous–Palaeogene sediments of which those before the MidSantonian were folded, faulted and uplifted in several places ( Benkhelil, 1989).
Coal occurrence, exploitation, Processing, and utilization have strong impact both on human health and the environment. This results from its composition and environment of occurrence. Maiganga Coal occurs in the Gombe sandstone. Result of the petrography analysis of the study area demonstrates high silica content and the presence of some elements in the mine.

Mining is the extraction of valuable minerals or other geological materials from the earth. The geological survey agency of Nigeria and the ministry of mines and steel development have reported the occurrence of more than 34 minerals in over 450 locations spread across the entire country, which are in various stages of development.
Coal is mined by both surface or ''opencut'' (or opencast) and underground or ''deep'' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia''s coal is produced from opencut mines.

Nigeria started major production of coal, tin and columbite by the 1940s. In 1956 when oil was discovered, the mineral industries suffered when the focus shifted to mining oil. In the 1960s the Civil War led to expat mining experts leaving the country and mines being abandoned.

Chemical studies have been carried out on coal samples from Maiganga coal mine, Gombe formation, Upper Benue Trough of Nigeria with a view to determine theirchemical characteristics and possible utilization as coking coal or otherwise. The coal samples used for the analyses were sourced from the Maiganga coal mine. Various conventional coal analytical methods were adopted according to the ...
Extensive research have been carried out to assess the radionuclide contents of coal deposits around the world [1, 2, 5, 13, 17–19, 26, 30–32], but information on the radioactivity of Nigerian coal is relatively limited. Yet Nigeria is endowed with abundant coal deposits with enough capacity to generate up to 30% of its energy needs.
