To precisely regulate the performance of site mixed emulsion explosive (SMEE), influences of key parameters, including aqueous phase (ammonium nitrate/water), oil phase (diesel oil/engine oil), shear rate and proportion of sensitizer, on the performance of SMEE were systematically investigated. A quantitative correlation model describing the variation of charge density and detonation velocity with various factors were established by means of multiple linear regression and path analysis. The results show that moderately increasing content of ammonium nitrate or reducing water content can significantly improve the detonation velocity; increasing the proportion of engine oil in the oil phase or reducing the proportion of diesel oil can enhance the energy output of explosive. A higher shear rate can reduce the internal phase particle size of emulsion, thereby increasing detonation velocity; however, a larger proportion of sensitizer can lead to a decrease in detonation velocity. Path analysis results indicate that priority should be given to the proportion of sensitizer and content of ammonium nitrate in regulation of detonation velocity of emulsion explosive, while both the proportion of sensitizer and shear rate should be taken into consideration in adjusting charge density.
