A hydrologic analysis of reclaimed spoil material water content over time was performed at a lignite coal mine in Northeast Texas. The objective of the study was to determine if any water control methods would be required in spoil banks to prevent excessive seepage into active mining areas. Hydrologic evaluation of strip mined stockpiles proved to be a very complex and inexact procedure. Spatial and temporal variations in measured infiltration rates can vary over three orders of magnitude and there is the additional complication that measurements are affected by the equipment used to evaluate the redevelopment of a ground water table within the spoil banks. These were infiltration testing and soil properties testing. A soil sampling program augmented the infiltration testing. Both mechanical and chemical properties of spoil bank soils were tested. Chemical properties analyzed were exchangeable calcium, magnesium, sodium and soil pH. Physical properties analyzed were grain size, porosity and water content. Based on the infiltration tests, physical and chemical soil property tests a projected development of a new water table was estimated. This information in turn was used to evaluate the necessity of water control methods. 13 references, 2 figures, 2 tables.
