The Lafia-Obi coal deposit has been found to be geologically faulty and the minimum estimated cost of mining it per ton was at N87.50 as at 1977 (Taskforce, 1987). Considering the present exchange rate of the Nigeria Naira to the US dollar, the current mining price per ton of Lafia-Obi coal can be taken to be US$87.50 (Adeleke and Onumayi, 2007).

Petrographic studies and proximate analysis of coal samples from Lafia-Obi, Chikila and Lamza deposits of the Benue Trough, were used in the ranking and preliminary assessment of the coking potential.
The present global concern for new sources of energy has kindled a renewed interest in coal. In the option for maximizing the use of low grade coals in the production of metallurgical grade coke and various coal conversion processes, the qualities of three Nigerian coal samples, Onyeama, Garin Maiganga and Lafia-Obi, were assessed for their potential utilization in a blast furnace.
The technology of fluidized bed coal combustion (FBC) and its advantages over conventional coal burning systems is now well established and is extensively reported in the literature. There is also some emphasis in literature about the suitability of Lafia-Obi coal in FBC. However, there is little quantitative or qualitative information on theperformance of Lafia-Obi in FBC.
Energy Council 8 puts Nigeria’s total proven coal reserves at 344 million tons, most of which fall within the rank of bitumi-nous or sub-bituminous. Of the total Nigerian coal deposits, the Lafia-Obi basin has an estimated 21 million tons of bituminous coal reserves.9 This makes it an attractive economically viable

Coal . The Lafia-Obi coal which is of high-medium volatile bituminous rank with estimated reserves of 128.3million tonnes could be used to establish small sized modular coal-fired Independent Power Plants (IPPs) for the generation of electricity in the state.
The cost of dewatering of the Lafia- obi coal mine will absorb a substantial part of both capital and operating cost of the investment. Drawing example from the coal seams of America, the flat-lying sedimentary rocks of southwestern Pennsylvania, underground mining is routinely accompanied by rock fracturing, dilation of joints, and ...

Nevertheless, the ash content of American coal, Lafia-Obi and Chikila coals are relatively lower than the ash content on dry basis of the pulverised coal used in this study. Similarly the low ash content is an improvement on the coking quality, low ash content is an essential requirement for coke making coals .
Metals concentrations in both Lafia-Obi and Chikila coal samples are within the limits allowed by the Federal Environmental Protection Agency (FEPA) except in Chikila (UBCJ-1) and Lafia-Obi (MBJJ-6) coal samples where iron was observed to be higher than the stipulated 20 ppm.
