Slope Stability and Ground Water Control in Eufaula Bauxite District Alabama (66175d18-b328-46b9-a703-6bff6a108fe0)

Hydrogeological techniques were used to solve problems of slope stability in open-pit mines of the Eufaula bauxite district, Ala. Geologic and hydrologic data were evaluated and used to design a system of dewatering wells to enable the operators to mine bauxite more efficiently and economically. Walls of open-pit mines in the district were subsequently stabilized by the operation of the dewatering system. Three open- pit mines, each at varying stages of the mining process, of the A.P. Green Refractories Co., were used to develop a sequential series of guidelines that indicate how to effectively remove ground water from the formations surrounding the ore bodies in the district. The use of sound engineering principles in well design, in combination with the correct interpretation of the pit hydrology provided the basis for solutions of the slope-stabilization problem and aided in the economical removal of bauxite from mines of the district.
