冶金工业部于1978年12月5～8日在邯邢冶金矿山管理局召开了多孔粒状铵油炸药鉴定会。冶金、化工、五机等系统的工厂、矿山、科研、设计、高等院校等47个单位的75名代表参加了会议。会议听取了长沙矿山研究院、石家庄化肥厂等单位关于多孔粒状铵油炸药和多孔粒状硝铵的试验和现场使用的技术报告,进行了多孔粒状铵油炸药的爆炸性能现场测试表演,并观察了该炸药在符山铁矿露天阶段深孔、巷道掘进和地下采矿中深孔爆破作业中的使用情况及技术经济效果。多孔粒状铵油炸药以石家庄化肥厂试制的多孔粒状硝铵为主要原料,其配比为:94.5％多孔粒状硝铵、5.5％柴油。该炸药的主要爆炸性能是:猛度:20～23毫米(约束条件:直径40毫米,壁厚5毫米的钢管);爆轰速度分别为:2300～2900(米/秒)(约束条件:直径38毫米、壁厚5毫米的钢管)
Ministry of Metallurgical Industry in December 1978 December 5-8 held in Handan Xing Metallurgical and Minerals Authority porous granular ammonium oil explosives appraisal meeting. 75 delegates from 47 units including factories, mines, scientific research, design, institutions of higher learning and metallurgical, chemical and five-machine systems attended the meeting. The meeting listened to the Changsha Mine Research Institute, Shijiazhuang Fertilizer Plant and other units on the porous granular ammonium nitrate explosives and porous granular ammonium nitrate test and field report on the use of technology, conducted a porous granular ammonium oil explosives performance test of the field performance and observed The use of the dynamite in the deep-hole in the open-air phase of Fushan Iron Mine, tunneling and deep-hole blasting in underground mining and its technical and economic effects. Porous granular ammonium oil explosives Porous granular ammonium nitrate trial production of Shijiazhuang Fertilizer Plant as the main raw material, the ratio is: 94.5% porous granular ammonium nitrate, 5.5% diesel. The main explosive properties of the explosive are: Burnout: 20-23 mm (Constraints: steel pipe 40 mm in diameter and 5 mm in wall thickness); detonation velocities of 2300-2900 m / s (constraints: diameter 38 mm, wall thickness of 5 mm steel)
