Abstract

La présente invention concerne de manière générale une composition explosive en émulsion eau dans huile, comprenant une phase organique et une phase oxydante comprenant au moins du nitrate d'ammonium, au moins 50 % en poids de l'huile non renouvelable normalement utilisée dans la phase organique étant remplacée par une ou plusieurs huiles renouvelables, en particulier une huile végétale droite. La présente invention concerne une composition d'émulsion explosive du type eau dans huile, comprenant entre 80 % en poids et 95 % en poids d'une phase oxydant compte tenu du poids total de la composition d'émulsion ; au moins 40 % en poids de nitrate d'ammonium (AN), et au moins un ou plusieurs sels de nitrate secondaire ; notamment au moins 15 % en poids de nitrate de calcium, ou au moins 20 % en poids de nitrate de calcium et/ou de nitrate de sodium, compte tenu du poids total de la composition de phase d'oxydant ; entre 5 % en poids et 20 % en poids d'une phase organique compte tenu du poids total de la composition d'émulsion. La phase organique comprend entre 12 % en poids et 50 % en poids d'un ou plusieurs émulsifiants, entre 50 % en poids et 88 % en poids d'une composition de carburant, compte tenu du poids total de la composition de phase organique. La composition de carburant comprend entre 20 % en poids et 100 % en poids d'une huile végétale brute (HVB), compte tenu du poids total de la composition de carburant.
