Emulsion explosive is widely applied for its safety and environmentally friendly and stable characteristics, but the rock breaking efficiency of the emulsion explosive is not ideal for its low explosion power. In order to improve the detonation characteristics of the traditional emulsion explosives, hydrogen storage material was put into it. Through underwater explosion experiment and emulsion explosives Brisance experiment, the energy output characteristics of different emulsion explosives were studied. Results of selected detonation parameters for prepared compositions of explosive materials with hydrogen storage materials are presented. For comparative purposes, the paper also presents analogous results for conventional emulsion explosives which sensitized by glass microspheres, hydrogen storage material MgH₂ and TiH₂ are both have good improvement on the explosive power, and respectively increase remarkable on decay time and overpressure of the shock wave. Before the detonation reaction, hydrogen storage material MgH₂ and TiH₂ were hydrolyzed to create H₂, then small bubbles were distributed uniformly in the emulsion matrix, at last the emulsion matrix was sensitized. H₂ was energetic material and participated in the detonation reaction, so the total energy output increased. Compared with emulsion explosives sensitized by microspheres, shockwave energy of emulsion explosives sensitized by MgH₂ increased32%, and shockwave decay time of emulsion explosives sensitized by TiH₂ increased 42%.
