我矿是一个凹陷露天开采多年的老矿,随着开采深度逐年延深,炮孔内的积水越来越多,现用铵油炸药不能适应水孔爆破,直接影响矿山生产。我们获悉冶金矿山采用浆状炸药解决了水孔爆破问题,矿党委对此非常重视,立即组织了“三结合”浆状炸药试验小组,从1976年10月就开始积极筹备,于1977年4月做了两次工业性试验,试验结果表明槐4号浆状抗水炸药具有塑性好、抗水性强、炸药感度较高、贮存性能良好等优点。
Mine is a depression open-pit mining for many years old mine, with the deepening of mining depth year by year, more and more water inside the blasthole, the current use of ammonium explosives can not adapt to the water hole blasting, a direct impact on mine production. We learned that the use of slurry explosives in metallurgical mines to solve the problem of water hole blasting, mine party attaches great importance to this, immediately organized a “triple” slurry explosives test group, from 1976 October began active preparation, in April 1977 Two industrial tests were made. The test results show that the slurry-type water-resistant explosive Huai 4 has the advantages of good plasticity, strong water resistance, high sensitivity to explosives and good storage performance.
