Operation Nougat Shot Hard Hat, Project Officers Report-Project 3.6, Static Stress Determinations

Abstract

Magnitudes of maximum and minimum stresses in the plane normal to the axis of several boreholes were determined in the rock adjacent to drifts at the Hard Hat experiment at the Nevada Test Site. Measurements were made both pre- and postshot. It is evident that the rock in the end of C-Drift was strongly disturbed by the Hard Hat event.
