Project DUGOUT: Concrete, Grout, and Shotcrete Support, and Design and Postshot Evaluation of Stem

Abstract

Project DUGOUT consisted of the simultaneous detonation of five, 20- ton, chemical, row-charge explosives in hard, dry rock. The primary purpose of the project was to increase the knowledge of row cratering dimensions in hard, dry rock. The report describes the following work performed for the project by personnel of the U. S. Army Engineer Waterways Experiment Station: the design and placement of grout mixtures used in grouting satellite holes surrounding the anticipated trench, the design and supervision of the placement of a shotcrete mixture used in lining the walls of each of the shot cavities, the design and supervision of the placement of a concrete mixture used in stemming the access holes to each of the shot cavities, the design of the stem configuration for each of the five shot holes, and postshot evaluation of stem design and survey of stem ejecta.
