Abstract: Delay detonators can be made to function reliably at reduced distances from a neighboring detonation by increasing the weight of the detonator's priming charge. Detonators containing about 0.26 g or more of lead azide perform reliably 12.7 cm from a detonation in a shock resistance pipe test, and this performance is reflected in high performance in trenching operations. The higher energy output of the heavier primer charge may compensate for a decrease in the base charge's sensitivity as the detonator shell is deformed or collapsed by shock.
