Abstract:

Field cratering experiments in hard, dry rock have utilized a high explosive, nitromethane CH3NO2, which is emplaced through a 1-meter-diameter hole drilled to emplacement depth. To restrict the explosive and allow the crater to form, a reinforced-concrete stem having a shear strength approximately matching that of the surrounding medium is required. This paper describes the use of dynamic triaxial tests to determine the dynamic chear strength of the rock for use in stem design. Author
