Title
(EN) EXPLOSIVE COMPOSITIONS WITH REDUCED FUME
(FR) COMPOSITIONS EXPLOSIVES À FUMÉE RÉDUITE
Abstract
(EN)
Explosive compositions including coated urea and an explosive including ammonium nitrate and fuel oil are provided. The explosive compositions can generate reduced levels of nitrogen oxide upon detonation. Methods of loading a blasthole with the explosive compositions and methods of reducing post-blast nitrogen oxide are also provided.
(FR)
L'invention concerne des compositions explosives comprenant de l'urée revêtue et un explosif comprenant du nitrate d'ammonium et de l'huile combustible. Les compositions explosives peuvent générer des niveaux réduits d'oxyde d'azote lors de la détonation. L'invention concerne également des procédés de chargement d'un trou de mine avec les compositions explosives et des procédés de réduction de l'oxyde d'azote post-explosion.
