The existence of a limestone mine located some 2200 ft (671 m) below the ground surface and having a volume of 338 million cubic feet, provides a unique opportunity for the development of a high head pumped storage power facility. An extensive geotechnical program of drilling, testing, and grouting showed the presence of high pressure brine water in a Oriskany sandstone zone and at the depth of proposed powerhouse excavations. The data also indicated that ideal rock conditions for the power house excavation exists between the mine and the high-pressure brine water. It was immediately realized that it might be preferable or even necessary, to raise the powerhouse to avoid any hydraulic connection with the brine. The question is, what setting for the bottom of the powerhouse excavation is sufficient to meet the requirements. This paper presents the studies that were carried out to establish a powerhouse setting that would provide both a structurally stable excavation under the loading conditions imposed by the high-pressure brine, and eliminate the possibility of significant brine inflow to the excavated caverns.
