Abstract (en)
[origin: EP4056545A1] The present disclosure relates to a water-in-oil emulsion explosive composition, comprising an organic phase and an oxidizer phase at least comprising ammonium nitrate, wherein at least 50 wt.% of the normally used non-renewable oil in the organic phase is replaced with one or more renewable oils. The present disclosure relates to an explosive emulsion composition of the water-in-oil type, comprising between 80 wt.% and 95 wt.% of an oxidizer phase in view of the total weight of the emulsion composition, comprising at least 40 wt.% of ammonium nitrate (AN), and at least one or more secondary nitrate salts, comprising in particular at least 10 wt.% calcium nitrate or at least 20 wt% calcium nitrate and/or sodium nitrate, in view of the total weight of the oxidizer phase composition, between 5 wt.% and 20 wt.% of an organic phase in view of the total weight of the emulsion composition, the organic phase comprising between 12 wt.% and 50 wt.% of one or more emulsifiers, between 50 wt.% and 88 wt.% of a fuel composition, in view of the total weight of the organic phase composition, in which the fuel composition consists of between 0 wt.% and 50 wt.% of one or more non-renewable oils, and between 50 wt.% and 100 wt.% of one or more renewable oils, in view of the total weight of the fuel composition, the total weight% of the oils being 100.
