摘要
利用板痕试验研究了不同装药条件下膨化铵油炸药爆轰性能的变化。实验发现膨化铵油炸药的临界直径介于12～15mm,"压死"密度为1.25～1.40g/cm3,炸药顺利爆轰时水分含量需低于2.0%。膨化铵油炸药的爆轰能力随着装药直径增大、装药高度增加、装药密度提高、水分含量减少、粒度降低而提高。
The effect of different expanded ANFO charge condition on detonation performance was studied by plate trace test.Results showed the critical diameter of expanded ANFO was between 12 to 15 mm;the dead-pressed density was between 1.25 to 1.40 g·cm-3;and the content of water must be less than 2.0% for detonation.Its detonation performance increased along with the charge diameter augment,charge height enhancement,charge density increase,water content reduction and particles size decrease.
