Lafia-Obi coal, the only local coal with good coking properties is however laden with excessive ash and sulphur contents of about 26.3% and 2.3% respectively (Taskforce, 1987). 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).

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.
country’s coal mining industry to provide fuel for power generation and domestic use. According to [15], the Kogi and the Benue (Orupka, Ezimo, Lafia-Obi) district can each support a coal-fired power plant with an ultimate capacity of approximately 3,500 MW. Further report [15] showed a good probability that
Binary blend formulation between the prime coking western Canada coal and Lafia-Obi coal as-leached showed that inclusion of 16.63% of the latter was probable and this translates to reduction in
Geology, geochemistry and biomarker evaluation of Lafia-Obi coal, Benue Trough, Nigeria
Available data show that coal (mainly sub-bituminous stream coals except for the Lafia-Obi bituminous coking coal) is available in more than 22 coalfields spread over 13 States in Nigeria. The proven coal reserves are about 639 million metric tonnes while the inferred
Apr 01, 2018· Some of the notable coal mines in the Lower Trough include Onyeama and Okaba and Lafia-Obi for the Middle Trough. All in all, there are about 23 coal mines in Nigeria [ 1 ], some of which are currently not in operation [ 4 ]. Previously, coal was mainly used to power trains and also for electricity generation [ 5 ].

While the former has a permit for coal, lead and zinc in Obi and Lafia, the later has a Small-scale Mining (SM) licence for coal in Lafia. A survey across their sites in the state showed nothing
Subsequent prospecting was conducted and twenty-two coal mine sites/deposits were discovered with varying reserves. Lafia/obi coal is one of them with proven reserve of 21.42 million tonnes [3]. Lafia/obi coal is bituminous and this grade of coal is important as

The proposed Lafia-Obi coal mine which is expected to provide the much needed coking coal for the Adjaokuta Steel Industry cannot be an exception to such environmental menace.The expected coal mining activities has the capacity to affect the quality of domestic water supply to the Nasarawa state capital and its environment with possible
The volatile matter places Lafia-Obi in the medium-volatile bituminous rank, while Lamja and Doho are of medium-volatile bituminous rank. The rheological properties show that Lafia-Obi is the only caking coal. This put together single out Lafia-Obi as a potential candidate for coke making.
coal samples. The volatile matter of Lafia-Obi coal is close to that of the foreign coals; while a large difference exists between Chikila coal and the foreign ones. It was observed elsewhere that the Lafia-Obi coal is higher in maturity than the Chikila coal [17] and volatile matter is known to decrease with increase in rank [18,19].
