Coal consists of mainly organic materials and minor inorganic constituents. These components determine coal’s possible value in the metallurgical, power generation, and other sectors. Coal is one of the most affordable and dependable energy sources used to produce electricity globally. Geological mapping of Okobo coal in the Anambra Basin of Nigeria was carried out and coal samples taken and subjected to proximate analysis, ultimate analysis, calorific value determination, and free swelling index test in order to source coking coals for metallurgical industries and thermal coals for power generation in the nation. The average composition of the coal, according to the results of the proximate analysis, is 11.94% moisture, 5.66% ash, 36.73% volatile matter, and 45.67% fixed carbon. The ultimate analysis also showed that the average composition of coal is as follows: 60.20% carbon, 4.46% hydrogen, 1.59% nitrogen, 15.52% oxygen, 0.65% sulphur, and 0.027% phosphorus. The coal samples have an average heating (calorific) value of 10452 Btu/1b (24311 kj/kg) and a free swelling index (FSI) of zero (0). These traits imply that coal is non-coking and unsuitable for use in the production of iron and steel in the metallurgical sector. The coal, however, is suitable for boilers, industrial heating ovens, and the production of power.
