Experimental Study on Emulsion Explosive Blasting under Different Under-Water Pressure

Abstract This paper aims to study the effects of different water depths on properties emulsion explosives by use an explosive underwater explosion test system for hydrostatic pressure under condition 0.2% sodium nitrite sensitized blasting model experiments. The results showed that experiment designed simulation equipment can be used in performance sample compression state explosion. It better simulate environment depth conditions. After blasting, fractal dimension concrete fragments decreases first and then rises with increase pressure, reaches inflection point between 0.3 mpa 0. 5mpa, which proves has a certain effect explosives, is not linear distribution. experimental could provide basis subsequent research characteristics explosives.
