The invention relates to a method for stabilizing a detonable mixture of emulsion and AN or ANFO prills. If the mixture involves ANFO prills, the steps comprise dissolving a surfactant in a liquid organic fuel prior to adding the fuel to AN prills, adding the fuel containing the dissolved surfactant to the AN prills to form ANFO prills and blending the ANFO prills with an emulsion to form a stable explosive composition. If AN prills are used, the steps include adding the surfactant to the prills and then mixing them with the emulsion. The compositions of the invention comprise stabilized emulsion explosives having a mixture of AN or ANFO prills and emulsion wherein the AN prills contain a surfactant and the ANFO prills comprise a mixture of AN prills and a liquid organic fuel in which a surfactant is dissolved.
