本文介绍了水厂铁矿大区多排微差爆破试验研究的技术途径及成果。实践表明,以扩大孔网参数、提高炮孔邻近系数为中心的技术方案和选取的爆破参数是合理的,因而,获得了良好的技术经济指标。
This paper introduces the technical approaches and achievements of multi-row millisecond blasting in waterworks iron ore area. Practice shows that it is reasonable to expand the parameters of the hole network and improve the proximity coefficient of the hole, and select the blasting parameters. Therefore, good technical and economic indicators have been obtained.
