我队根据贵阳铁路局的经验，试制成功一种新型的高威力炸药，目前已经在我队广泛制造和使用，此炸药属于硝酸铵类型炸药，其组成成分是：硝酸铵90％，煤油5％，木粉5％。油铵炸药中的硝酸铵是一种氧正平衡炸药，反应生成物中游离氧占20％，其反应方程式：2NH_4NO_3→4H_2O+2N_2+O_2 2×27.5千卡（热）加入煤油（柴油亦可，但必须含水量少）的目的，是使硝酸铵中的剩余氧与煤油内的炭氢化合，使爆炸时产生热量，从而提高炸药的爆力。加入煤粉、木粉的目的是减少粘结。
According to the experience of Guiyang Railway Bureau, our team succeeded in trying out a new type of high-power dynamite that has been widely manufactured and used by our team. The explosive belongs to the category of ammonium nitrate explosives. Its composition is 90% ammonium nitrate, 5% kerosene, , 5% wood flour. Ammonium nitrate explosives ammonium nitrate is a positive oxygen balance of explosives, the reaction products of free oxygen accounted for 20% of the reaction equation: 2NH_4NO_3 → 4H_2O +2 N_2 + O_2 2 × 27.5 kcal (heat) Add kerosene (diesel may also be , But the water content must be less) is to make the remaining oxygen in ammonium nitrate and kerosene within the carbon hydrogen, so that the explosion heat, thereby enhancing the explosive explosive. The purpose of adding pulverized coal, wood flour is to reduce the bond.
