To improve the explosion power and the pressure resistant properties of emulsifying seismic bomb, and reduce the environmental pollution and safety hazards, a kind of hydrogen storage type emulsifying seismic bomb was designed using emulsion explosive sensitized compositely by TiH2-glass microsphere as the initiating explosive grain, and emulsion explosive sensitized chemically by MgH2 as the main charge. The explosion power of TiH2-glass microsphere sensitized emulsion explosive and the explosion power and the pressure resistant properties of MgH2 sensitized emulsion explosive were studied by compression experiments, detonation velocity tests, underwater explosion experiments, and shock wave pressure experiments, respectively. The results show that compared with the traditional emulsifying seismic bomb, TiH2-glass microspheres sensitized emulsion explosive in hydrogen storage type emulsifying seismic bomb has high explosion power, the compression amount of lead column is 23.80mm, reaching military explosives brisance and at the same time the detonation velocity is 4659m/s, it is suitable to be used as initiating explosive grain instead of TNT explosive grain. MgH2 sensitized emulsion explosive has high explosive power and good compressive resistance, the peak pressure, specific impulse and shock wave total energy were respectively increased by 8.7%, 12.4% and 33.0% compared with the traditional glass microsphere sensitized emulsion explosive, which is suitable for main charge instead of the main charge of emulsion explosive. The use of hydrogen storage type emulsifying seismic bomb instead of the traditional seismic bomb has a good application prospect. © 2018, Editorial Board of Journal of Explosives & Propellants.
