The droplet size and distribution of dispersion phase for emulsion explosives matrix were tested by laser particle analyzer. The effect of the crystallizing temperature of water-phase,the stirring speed,and the contents of emulsifying agent on the droplet size and distribution of emulsion explosives were studied. The results show that the effect of crystallizing temperature of water-phase on droplet size and distribution of dispersion phase is evident under certain conditions. There is a critical stirring speed of emulsion (1230 r·min^-1） below which the effect of stirring speed on the droplet size and distribution of dispersion phase is evident but is not obvious when the stirring speed of emulsion is over the critical value. The value is 1230 r·min^-1 under the experimental conditions. The additions of superabundant emulsifier agent to emulsions have no obvious effects on droplet size and distribution of dispersion phase.
