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

The concentration of inorganic chemical substances released into surface water from Okaba coal deposit were measured using spectroscopic techniques in order to assess the extent of pollution. Parameters measured (Pb Fe Cu Cr SO42 Cl Mn Zn and pH) showed that water samples within the mine area contain Pb Fe Cr Cl Mn and Zn in
tained from the sampling points and examine geochemical parameters of OkabaOdagbo coal deposit in order to elucidate on its best application for use. 2. Materials and methods The field work afforded the collection two sets of samples water and sediment (coal). Water samples were collected at random from groundwater (mine ponds) and OmajiOda
FIG. 4 is the 3D modeling of an Okaba coal pillar with AutoCAD showing the pillar dimension of 32 m length m width and m height which is sufficient to support the mine with safety.
Hence the coal deposit in the light of the above characteristics is noncoking and thus cannot be employed in the generation of substantial heat for the working of blast furnace for iron smelting. It can however be employed as a steam coal which can be used as fossil fuel in rail locomotives steam boat electricity generation smokeless

In 1909 coal was discovered in Enugu Nigeria. The Ogbete drift mine opened six years later. The Ogbete mine s operations and others in the country were merged into a new corporation in 1950 The Nigerian Coal Corporation. The NCC was tasked with exploiting coal resources 2 and held a monopoly on coal and coke mining production and sales
