Hydrogeologic Characteristics of Surface-Mine Spoil in Okaba Coalfield of Kogi State

Authors : Charles Udosen and A.A. Eshiett

Abstract: The nature, degree and duration of groundwater and spoil interactions need to be factored into comprehensive mine drainage predictive methods or models. However, the hydrogeology of mine spoil is poorly understood and remains one of the least analyzed aspects of mine drainage prediction. This study was designed to evaluate geological formation of the Okaba coalfield; topography of the mine site and the lithologic/hydrogeologic components of the mine site using borehole sections, map-based analysis and field measurements. The Okaba coalfield is underlain by a variety of the Mesozoic (secondary) sedimentary rocks, which are mainly non-aquiferrous. The DEM indicates that surface runoff (along with the spoil water from the coalfields) drain directly into natural drainage system (streams/rivers). This hydrologic information used in conjunction with the overburden geochemical data can be used to improve mine drainage predictive models and methods.
