The Lee Creek Mine of Texasgulf, Inc. is a major phosphate-mining operation located in the central North Carolina Coastal Plain. Early mining investigations indicated that 1) the phosphate ore could be economically recovered only by dry strip-mining methods, and 2) that artesian ground waters in the formation (Castle Hayne Limestone) underlying the ore would have to be controlled.

This paper relates the application of ground-water hydrology in depressurizing the Castle Hayne aquifer to facilitate dry strip mining at depths of 130 feet below mean sea level. The information presented here was excerpted from Hird (1971).
