Abstract
A method of manufacturing an emulsion explosive which is insensitive to a number 8 detonator comprising forming a water solution of at least one oxidizing salt dispersed in a fuel such as oil, wax, urea, aluminum and the like and then heating the solution to a temperature of 70.degree.-100.degree. C. Thereafter gaseous particles are added to the heated solution both as an aid to detonation and as a co-emulsifier. Fuel with emulsifier dissolved therein is then added and emulsification takes place thereafter at relatively low stirring speed due to the presence of the co-emulsifier of gaseous particles and its introduction into the salt solution before any of the other components used for the explosive.
