Assessment of the efficiency of the explosion of the simple explosive mixtures with energy additives.

On the basis of experimental studies in the field and on polygon, the features of the detonation of mixed explosive charges on various types of ammonium nitrate with energy additives during pneumatic load-ing are revealed. It has been established that when using porous grades of nitrate, the addition of alu-minum powders differently dispersed leads to a decrease in detonation parameters due to the peculiari-ties of aluminum oxidation at the front of the detonation wave and does not provide the theoretically expected increase in the energy of the explosion. The use of high-quality fine-grained porous nitrate in the ANFO mixtures allows obtaining the higher explosive characteristics of the mixtures. The supple-ment of energy additives in the form of aluminum powders does not increase the explosive characteris-tics of the mixture.
