含水岩层内非抗水炸药的使用方法在库兹巴斯各煤田露天矿复杂采矿和水文地质条件下,在含水岩层中爆破工作愈加困难,因而必须采用昂贵的抗水炸药,并使装药劳动生产率降低33～50％。同时,由于爆破器材受潮拒爆次数增多。此外,众所周知的是,库兹巴斯各露天矿80～85％岩石可 Use of non-water-resistant explosives in aquifers In the complex mining and hydrogeological conditions of the open pit mines in Kuzbass, blasting in aquifers is increasingly difficult, necessitating the use of expensive anti-explosives and the charging of labor Productivity reduced by 33 ~ 50%. At the same time, due to blasting equipment damp refused to increase the frequency. In addition, it is known that 80 to 85% of the rocks in the open pit of Kuzbasas are available
