To obtain water resistant ANFO explosive, in this article, the effect of usage of some components were investigated. To this aim, after some screening tests, four components including guar gum, borax, Eremurus 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 optimize product including 90% ANFO and 10% of mixture of four compounds introduced in screening test, were obtained which the water penetration into 100gr of this product (in 250ml graduated cylinder, after 12 hours) was about 10 mm.
