编辑同志:我厂使用直径22公厘炭素钢钎打眼,以某化工厂出品的32公厘硝铵炸药及#8雷管起爆,但是炮眼直径比药包直径小,结果不能使用,因此将它改装成22公厘(在改装过程中,药有吸潮性促使效率降低)。用黑色火药代替#8雷管装药,方法炮眼中放一节硝铵炸药,末端将纸撕去,再放黑火药用炮焊捣紧,然后拿一木制小针在黑药中心处插一个孔,并用黄泥筑紧,再将木针取出,在小孔内放入黑药引线一根即可。第一种方法:每一公尺装硝铵药175克,平均一公尺眼爆下一吨左右的岩石,岩石很碎,大块岩 Edit comrades: I plant the use of 22 mm diameter carbon steel rod drilled eye, with a chemical plant produced 32 mm ammonium nitrate explosives and # 8 detonator detonation, but the diameter of the hole than the kits small, the results can not be used, so it will be modified Into 22 mm (in the conversion process, the drug hygroscopicity led to reduced efficiency). Replace the # 8 detonator charge with black gunpowder. Put a piece of ammonium nitrate explosive in the hole of the blasting gun. Remove the paper from the end and put the black gun into the gun and tighten. Then take a wooden needle and insert it in the center of the black drug A hole, and build tight with yellow mud, and then remove the wooden needle, put a hole in the hole can be a black drug. The first method: 175 grams of ammonium nitrate per meter installed, an average of one meter eye drops about a ton of rock, the rock is very broken, large rock
