DGSII: A high explosive stemming equipment
To obtain a phenomenological understanding of grout flow and LOS pipe closure processes and to obtain data for a comparison with a calculational modeling of the experiment, we drove three stemming models with a 454-kg sphere of high explosive. The hose rock was the water saturated, Tunnel Bed Tuffs of G Tunnel, Nevada Test Site. Measurements were made of stress history in the free-field tuff and in the stemming material, time of arrival of the debris in the LOS pipes, and the pressure in the cavity. Extensive mineback permitted observation and measurements of deformations of the models, and the cavity size and its details. 13 figs.
