Stabilized emulsion explosive and method
First Claim
1. A method for stabilizing a detonable mixture of emulsion and ANFO prills comprising the steps of dissolving a surfactant in a liquid organic fuel prior to adding the fuel to ammonium nitrate prills, adding the fuel containing the dissolved surfactant to the ammonium nitrate prills to form ANFO prills and blending the ANFO prills with an emulsion to form a stable explosive composition.

Abstract
The invention relates to a method for stabilizing a detonable mixture of emulsion and AN or ANFO prills and to the resulting compositions. A surfactant is dissolved in a liquid organic fuel prior to adding the fuel to AN prills for forming ANFO prills, or if AN prills are used without added liquid organic fuel, the surfactant is added to the prills. The ANFO prills or AN prills containing a surfactant than are mixed with the emulsion.
