Abstract
The feasibility of redesigning and adapting the all-secondary- explosive, low-voltage, electric safe detonator for use as a delay detonator was demonstrated. Operational characteristics were adjusted to allow direct competition of safe delay detonators with commercial delay blasting caps. Five experimental delay period models were developed and tested. Test results are given and evaluated. Subsequent simplified and improved designs for practical and economical mass production are described. Design concepts to meet Bureau of Mines voltage withstand, incendivity, and spark sensitivity requirements are included. Recommendations are made for experimental procedures to ready the safe-delay detonator for mass production and extensive use in mining and other industries.
