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.
