Reinforcing of ANFO Explosive Against Water Penetration

In this article, to obtain water resistant ANFO explosive, the effect of some components were investigated. To reach this aim, four components including guar gum, borax, eremurus (as glue) and superabsorbent sodium polyacrylate were selected. To determine and optimize the percentage of components in the mixture, design of experiments in Minitab software was used. Finally, the optimized product including 90% ANFO and 10% of mixture of four compounds were obtained, which the water penetration into 100gr of this product (in 250ml graduated cylinder, after 12 hours) was about 10 mm.
