【摘要】 为了研究高海拔压力环境下炸药猛度的变化规律,将膨化硝铵炸药和三级煤矿许用乳化炸药放置在密闭容器中,通过抽气模拟海拔0~4500m下压力环境,测量此环境下炸药猛度。实验结果表明:在高海拔压力环境下,膨化硝铵炸药猛度基本不发生变化,而三级煤矿许用乳化炸药猛度随着海拔高度的增加而增大。更多还原

【Abstract】 Aimed at the variation of explosive brisance under high altitude conditions, the expanded ammonium nitrate explosives and class 3 coal mine permissible emulsion explosives were laid in a closed container, the brisance of these explosives were measured under the pressure conditions corresponding to that of the 0~4 500m altitude, which was simulated through extracting air. The results show that the brisance of expanded ammonium nitrate explosives didn’t change basically under high altitude conditions, while the brisance of class 3 coal mine permissible emulsion explosives increased as altitude increasing.更多还原
