THE FORMATION OF PRIMARY IGNITION SOURCES WITH IMPACTIVE EXPLOSIVES INITIATION

In the article, an attempt was made to develop a theory of formation of primary decomposition sources in energy-saturated materials. Meanwhile, probabilistic values are used: relative speed of primary decomposition "sources" occurrence and the quantity of those sources. A special role in the initiation is given to the occurrence of so-called clusters of primary sources, which sizes exceed the critical one, which is determined by the charge size and the conditions of initiation. The proposed model defines the optimal initiation speed leading to guaranteed detonation excitation and becomes a prerequisite for blasting explosives probabilistic initiation theory development.
