摘要
为了研究高原环境对炸药爆速的影响,将粉状乳化炸药与三级煤矿许用乳化炸药置于自制密闭容器中,通过抽气模拟海拔0-4 500 m下的高原环境,用爆速仪对此环境下炸药爆速进行试验研究。试验结果表明：在高海拔压力环境下,粉状乳化炸药爆速几乎没有变化,而三级煤矿许用乳化炸药爆速随着海拔高度的上升,出现先增大后减小的趋势。
In order to investigate the detonation velocity performance under high plateau environment,powdery emulsion explosive and class 3 coal mine permissible emulsion explosives were both laid in a closed container,the pressure conditions at an altitude of 0-4 500 meters were simulated by air extraction,and then experimental research on detonation velocity under this environment was conducted by time measuring instrument. The results show that the detonation velocity of powdery emulsion explosive almost exhibited invisible change under high altitude conditions,while the detonation velocity of class 3 coal mine permissible emulsion explosives increased at first and then decreased as altitude increasing.
