ABSTRACT:
An explosive composition having a combination of a principal explosive, which is relatively insensitive to initiation of detonation, two mesh fractions of a sensitizing explosive which is relatively sensitive to initiation of detonation, a critical diameter additive which lowers the critical diameter of the composition, and a binder, demonstrates the ability to achieve steady-state detonation after deliberate initiation of detonation. The composition is further characterized by low sensitivity to accidental detonation by external influences, and favorable mechanical and processability properties.
A method of making an explosive composition of this type by adjusting the amount of critical diameter additive and testing the composition is also described.
