Abstract

L'invention concerne un explosif à particules à écoulement libre comprenant de 20 % à 90 % par masse d'un agent d'oxydation solide particulaire, et de 10 % à 80 % par masse d'une émulsion résistant à l'eau, ladite émulsion présentant des propriétés de revêtement non adhésif lorsqu'elle recouvre au moins en partie les particules de l'agent d'oxydation, permettant ainsi auxdites particules de s'écouler librement.
