CA 2213623

This invention relates to Explosives of non-Nitroglycerine type used in the mining industry. Especially, the present invention relates to generation of gas voids in Ammonium Nitrate based explosives such as Emulsion explosives/Slurry explosives/Heavy ANFO and Doped emulsions. A special aspect of the invention relates to lowering the density of such explosives at ambient to low temperature conditions. Accordingly, the invention provides an improved method of manufacture of water-in-oil emulsion explosive which comprises combining a continuous oil phase containing oils and waxes and a discontinuous aqueous phase containing oxidiser salts and emulsifying the composition in the presence of conventional emulsifiers to obtain the said explosive characterised in that diazonium salts are incorporated into the matrixof the said explosives and decomposed in-situ so that nitrogen gas bubbles are generated within said explosive matrix to produce voids within said matrix. An improved method for gassing of emulsion explosives in provided.

L'invention porte sur des explosifs autres que ceux de type nitroglycérine, pour l'industrie minière, et particulièrement sur la formation de poches de gaz dans les explosifs à base de nitrate d'ammonium, comme les explosifs à émulsion/explosifs en bouillie/ANFO lourds et émulsions dopées. Un aspect spécial de l'invention concerne la réduction de la densité de ces explosifs dans des conditions de températures ambiantes à basses. L'invention présente donc une méthode améliorée pour la production d'explosifs à émulsion d'eau dans l'huile, consistant à combiner une phase huileuse continue, renfermant des huiles et des cires, avec une phase aqueuse discontinue, contenant des sels oxydants, et à émulsifier la composition en présence d'émulsifiants classiques pour obtenir ledit explosif, caractérisé par le fait que les sels de diazonium sont incorporés dans la matrice desdits explosifs et décomposés sur place, de telle façon qu'il y ait production de bulles d'azote gazeux à l'intérieur de ladite matrice explosive. On présente une méthode améliorée pour le gazage d'explosifs à émulsion.
