Effect of Perlite Content on Performance of Emulsion Explosive in Under-Water Environment

Abstract Emulsion explosive has been widely used in underwater blasting construction. To study the effect of perlite content on performance emulsion explosives under deep water conditions, with different applied pressures and contents was studied by using self-built explosion test system. The results show that, increase pressure water, energy as sensitizer a decreasing trend, which is consistent actual situation, when 4%, sensitized bubble adiabatically compressed, hot spot fully explodes, its detonation best.
