Core logging test procedure

Core logging and sampling will be undertaken for all cored boreholes within the Exploratory Shaft Facility (ESF). These boreholes will be drilled primarily for the purpose of hydrologic testing, downhole mechanical/thermal testing, and for the placement of instrumentation. Core logging and sampling will assist in overall site characterization and provide geologic information at the specific sites where testing will occur. This activity will aid in the confirmation of the stratigraphy and structure of the host rock beyond the limits of the excavation. This document provides a description of the required procedures for core logging and sampling within the ESF. Qualified technical personnel, using these procedures, will collect the required core descriptions and samples. 3 refs., 4 figs
