针对高海拔地区的乳化炸药的配方优化及性能研究OA

In response to the impact and constraints of extreme environments such as low air pressure,large tempe-rature difference between day and night,and lack of oxygen in high-altitude areas on the performance of emulsion explo-sives,two new integrated oil phase materials have been developed through formula optimization,process improvement,and performance testing for the preparation of plateau-type emulsion explosives.At-20℃and an altitude of 3 600 m,the detonation velocity of the emulsion explosive is4 865 m/s,the detonation distance is8 cm,and the intensity is17.34 mm.After 12 cycles of high and low temperature experiments,the detonation velocity is 4 563 m/s,the detonation distance is 7 cm,and the intensity is 16.02 mm.Performances of the emulsion explosive was evaluated experimentally by simulating high-altitude conditions,and it was found that the performance indicators of the prepared plateau-type emulsion explosive meets the requirements of GB 28286-2024 under various high-altitude conditions.
