Foundation Report for Yatesville Lake Construction of Dam and Appurtenant Works. Phase 1. Yatesville, Kentucky
The geology of the Yatesville, Ky dam site and a discussion of how the engineered structures were adapted to the existing rock conditions is the purpose of the reports. The Yatesville dam is located in eastern Kentucky near the town of Louisa. Geologically, it is in the Appalachian Plateau Provience. The Pennsylvania Age rocks are mostly sandstones and shales. Structures in this contract include a 900 foot long by 13 foot diameter concrete line tunnel, foundation excavation for the intake control tower, stilling basin and outlet channel. Rock excavation and treatment for each is discussed. A unique rock excavation program was employed for the tunnel excavation. A DOSCO SL 120 Roadheader mining machine was used instead of conventional drilling and blasting. The DOSCO is an electrohydraulic powered, crawler mounted, single boom cutting machine. Rock excavation was accomplished by a single boom mounted cutting head and the excavated rock was picked up on a conveyor and emptied into a loader. This resulted in smooth walls, little overbreak, no concrete overruns and a reduction in the number of rock bolts.
