Underwater Explosive Excavation Testing at San Nicolas Island. California 1972-1973.
Abstract
These tests were designed to provide preliminary information on a variety of topics relating to nearshore underwater explosive excavation. Topics investigated included: (1) Suitability of standard Navy demolition materials for use in underwater excavation projects; (2) Potential for modifying certain standard Navy demolition charges to allow their use or to improve their performance in underwater applications; (3) Suitability of certain commercially available conventional explosives and of commercial field-mixable, two-component explosives for underwater applications; (4) Identification of operational restraints for nearshore explosives work; (5) Validation of techniques that appear to be suitable for nearshore explosive excavation work; and (6) Determination of the limitations inherent in the techniques that can be applied. Data obtained from a total of 55 test shots consisting of 198 separate charges are presented. In addition, results from underwater operations with a modified track drill and comments on two commercial field-mixed, two-component explosives are included. Specific observations are made regarding: operations and techniques, drilling, logistics and materials, and measurements and data.
