- Calculations to simulate and evaluate nuclear test containment require data on the strength of the geologic media at the work point and in the surrounding region. Studies cited in the literature reveal correlations between mechanical properties of rocks and various drilling parameters of large horizontal boring machines that share similarities with drilling assemblies used at the Nevada Test Site (NTS). An extensive selection of downhole core samples spanning the strength range of NTS rocks has been collected, stratigraphically and petrologically identified, and tested for strength as a function of confining pressure. Detailed data on the drilling rates are available for similar geologic units identified in the compilation and also for the specific rocks from these vertical holes that were tested. These data are used to discuss a preliminary empirical correlation between reported laboratory-measured compressive strength and drilling rates for various NTS rock types.
