去年11月×矿区，槽探任务大，时间急，人员少，为了解决这一矛盾，我们学习了华铜矿和冶金部推荐的几个矿山使用铵油炸药的经验，因地制宜，用土法加工试制，获得了成功。工班效率由3.8米~3逐步提高到8米~3，12米~3，成本大大降低，为完成突击任务起着十分重要的作用。12月又用于手掘平巷的爆破，今年一月份扩大到电钻平坑中，效果均为良好。根据生产任务的需要，到目前为止，我们使用铵油炸药2吨多，实践证明，铵油炸药与2号岩石硝铵炸药的威力相近，可以代替2号岩石硝铵炸药用于各项坑探工程中。
In November last year, × mining area, tank exploration mission, urgent, less staff, in order to solve this contradiction, we learned from the China Copper and Metallurgy recommended several mine experience in the use of ammonium explosives, according to local conditions, trial production of soil processing , Got the success. Class efficiency gradually increased from 3.8 m ~ 3 to 8 m ~ 3,12 m ~ 3, the cost is greatly reduced, in order to complete the task of assault plays a very important role. In December, it was also used for demolition of excavation roadway. In January this year, it was expanded to drill pits and the results were good. According to the needs of production tasks, so far, we use more than 2 tons of ammonium oil explosives, the practice proved that ammonium nitrate explosives and No. 2 rock ammonium nitrate explosives similar power, you can replace No.2 rock ammonium nitrate explosives used in various pit exploration Engineering.
