ONYEMAOBI' DEPARTMENT OF MINING AND METALLURGICAL ENGINEERING THE FEDERAL UNIVERSITY OF TECHNOLOGY, AKURE, ONDO STATt:::, NIGERIA. ABSTRACT The only functional underground Coal Mine in Nigeria is located in Enugu in Anambra State. For some years now the mine has been beset with a perenial problem of flooding.
Dec 27, 2018· "The study correlated the geochemical/ petro graphical parameters against combustibility time for samples of Nigerian coal deposits obtained from Okaba, Owukpa, Ogboyoga, Omelehu, deposited in the Anambra Basin in one and LafiaObi coals in the Middle Benue and Maiganga in Gombe," he said.
There used to be 15 mining concessions in Wawonii. Nine have expired without being renewed; the other six, all for mining nickel, are frozen, including GKP. "When a company like GKP operates fully, the other five will follow suit," Mando said. He suspects the mined nickel .
The minimum fluidisation velocity was obtained to be and m/s for a coal batch feed of 150 and 450 g, respectively. Jauro and Chukwu [9] investigated three Nigerian coals (Onyeama, LafiaObi, and Garin Maiganga) to determine their suitability in developing formed coke for use as blast furnace coke. Parameters that were used include the ...
capacity is expected to be coal fired growing to percent by 2030 (Sambo, 2008). Consequently, coal demand is projected to increase. In addition to such domestic uses, Nigeria estimates that export demand for its coal could reach 15 Mmt per year (M2M, 2006). Table 243 provides an overview of coal mines and mining methods used in Nigeria.

LafiaObi/Foreign coals blends possess lower ash and better rheological properties compared to Chikila/Foreign coal composites which have high ash and poor rheological properties. These together suggest that amongst the two Nigerian coals, LafiaObi is superior for blending with the foreign ones in metallurgical coke production.
Apr 09, 2010· Coal mining is a very dangerous business, and although Massey's got a spotty safety record, these things happen and miners accept the risk every day they go down the shaft and work. It's part of the job, and no matter how many regulations and inspections you may have, methane pockets occasionally blow.
and environmental implications of the coal, bitumen and oil shale deposits had also been considered for its optimal resources quality. Since the mining of these deposits has been established in other countries, comprehensive information on the effects of mining activities on the environment is needed.
constructed inplace, the Ovoot Tolgoi Mine (Ovoot) began stripping and producing it's first coal. Coal was stockpiled on site, with initial coal sales beginning September, 2008. Through June, 2009, total coal sales are approximately million tonnes (Mt).
