现场混装铵油炸药爆速与猛度测定研究

Study on Detonation Velocityand Brisance Measurement of Mixed ANFO Explosive

为了研究现场混装铵油炸药的爆炸性能,分别采用牛皮纸与无缝钢管进行约束装药,通过光电测试仪法和铅柱压缩法对现场混装铵油炸药进行爆速与猛度的实验测试。实验结果表明:通过加强装药的外壳进行约束,可以测得现场混装铵油炸药爆速与猛度。采用测试仪法对现场混装铵油炸药进行爆速测量方法简单,得到结果可靠。爆速与猛度的测试结果满足现场混装铵油炸药的技术要求。

In order to study the explosive performance of field mixed ANFO explosive,paper and steel tube were used for charge,the detonation velocity and brisance of field mixed ANFO explosive were measured by photoelectric tester and lead column compression method.The experimental results showed that by strengthening the shell constraint of charge,the detonation velocity and brisance of field mixed ANFO explosive could be measured.The method of measuring the detonation velocity of field-mixed ANFO explosives by using the tester was simple and the results were reliable.The test results of detonation velocity and brisance met the technical requirements of field mixed ANFO explosives.
