    Abstract
  • In order to study the influence of plateau environment on emulsion explosive sensitized by different methods, three typical sensitization materials were selected to prepare emulsion explosive samples. The changes in microstructure and detonation performance of samples stored in simulated plateau environment (−20 ℃, about 0.05 MPa) were analyzed. The results showed that the low temperature and low pressure of plateau environment mainly affects the performance of explosives from the aspects of aggravating the stability of emulsion system and the distribution of hot spots. In the plateau environment, the crystallization degree of chemically sensitized explosives is lower than that of physically sensitized explosives but the hot spots change greatly, leading to a decrease in detonation performance. In the physical sensitization, the growth mode of expanded perlite explosive crystal is more complex, so it is easier to demulsify and crystallize, and the storage stability and detonation performance are significantly reduced. The degree of crystallization and detonation performance of resin microsphere explosive are relatively stable under low temperature and low pressure. In general, resin microspheres emulsion explosive has better adaptability to plateau.
