mining of lafia obi coal
Mineralogy and Geochemistry of SubBituminous Coal and Its .
· Some Nigerian coal deposits such as LafiaObi ( %; %) and Chikila coals ( %; %) also have considerably higher moisture content . The relatively low moisture content in the pulverised coal sample represents a significant improvement in coal's quality because moisture affects the calorific value and the concentration of other constituents [ 63 ].

ENERGY OUTPUT ASSESSMENT OF LAFIAOBI COAL IN A .
· This work investigated the energy output from the fluidized bed combustion of LafiaObi coal using five range of fuel equivalent diameters (FED) of 125 µm, 250 µm, 355 µm, mm and mm. Energy output in response to variation in bed temperature, FED, bed pressure, and fluidizing velocity was examined in the fluidized bed heat exchanger.

LafiaObi area (block 9) and NE of LafiaObi area (block 6). Inthe KeanaAwe area, the depth to basement varies between 3000 and 4900 m. This confirms the results of gravity studies ( Ajayi and Akakaiye, 1986) which earlier indied the existence of a deeper subbasin in this area. In the LafiaObi area the thickness of the sedimentary

· Two Nigerian coals, LafiaObi and Chikila were blended in the mass ratio of 70:30 with imported American and Polish coking coals. Proximate analysis, free swelling index, Ruhr dilatometer and Gieseler plastometer were used in assessing the coking qualities of both the single coals and the blends. The results show that the blends are lower in moisture and ash .
