摘要 文中对银洞坡金矿矿体赋存条件多变、地质构造复杂的特点,于矿岩接触带采取预裂爆破、控制爆破后冲和不同孔深的综合控制爆破技术,较好地实现了矿岩分穿、分爆和分运,有效地降低了矿石的损失率与贫化率,提高了企业的技术经济效益。 According to complicated condition and characteristics of geological structure of YinDong-Po Gold Deposit, the synthetic techniques of prespliting and controlling blasting in contact zone of ore and rock were employed. In this way, the separate drill, blast and transport for ore and rock were realized. Therefore the dilution and loss rates of ore were effectively reduced and economic benefit was raised for the enterprise.
