Abstract

Lignite is the lowest rank of coal; its deposits found within the Paleogene Anambra Basin are Tertiary in age. They occur within the uppermost stratum of the Eocene Ameki Group, the Oligocene Ogwashi-Asaba Formation and the basal part of the Miocene Benin Formation. Energy is considered as one of the fundamental resources for industrialization. The current situation in Anambra State is that energy demand is greater than energy supply; this forms the basis of this research. Lignite can play an important role for power generation in Anambra State as a domestic resource that will be proximally available. Anambra State is enriched with substantial lignite deposits, but these deposits are currently under fire attack, which if not tackled will result in total loss of the deposits and unimaginable geologic hazards. The lignite seam fires were examined; the causes and possible solutions were documented. Strategies for sustainable exploitation and harnessment of this resource were also enumerated, which when properly implemented will solve the energy problem facing the State, thereby enhancing its socioeconomic status and also create opportunities for investments, employment and national development.
