摘要
提高岩石的爆破质量对露天煤矿的生产具有重要意义,随着现代化矿山的建设,长期以来在穿孔爆破设计中所用的传统方法,存在一定的不足,本文提出了采用PVC管间隔装药的爆破方法,提高爆破效率和经济效益。
Improving rock blasting quality has been important for the production of open-pit coal mines. With the construction of modern mine, the traditional methods used in piercing and blasting design have some deficiencies. This article proposes a blasting method of using PVC pipe spacing charging to improve blasting efficiency and economic benefit.
