Abstract (fr)

La présente invention concerne de nouvelles émulsions explosives encartouchées à usage civil, de type eau-dans-huile, sensibilisées par un gaz dispersé, comprenant, en poids : 60% à 70% de nitrate d'ammonium, 8% à 14% de nitrate de sodium, 4% à 7% d'eau, 0,5% à 5% de combustible hydrocarboné, 0,5% à 5% d'émulsifiant, 12% à 18% d'aluminium. La somme des teneurs en nitrate d'ammonium et nitrate de sodium est comprise entre 70% et 80%, et la somme des teneurs en nitrate d'ammonium, nitrate de sodium, eau, combustible hydrocarboné, émulsifiant et aluminium est comprise entre 95% et 100%. Ces émulsions explosives, qui présentent simultanément une excellente sécurité d'usage et de fabrication, ainsi que l'énergie et la puissance des dynamites, sont particulièrement adaptées pour l'abattage des roches dures.
