摘要
本文较系统地分析了银洞坡金矿矿石损失贫化过高的原因，针对这一构造复杂矿床的开采，在大量的工业试验基础上，从矿山开采程序、矿岩接触带控制爆破、分采工艺技术等方面，提出了降低矿石损失贫化综合开采技术措施。
Reasons of producing higher ore loss and dilution ratio in Yin--Dong--Po Gold Mine are analysed systematically in this paper.Directing againstthe mining of complex--structured deposit, the technical measurs for lowering. oreloss and dilution ratio adoptable in the aspects of controlled blasting incontact zone of rock and ore, mining procedure,loading technique, etc areproposed based on a number of commercial--scale trails.
