摘要
试验、研究和应用了空场、崩落联合采矿法替代中深孔阶段强制崩落法。避免了顶板千枚岩的过早冒落,改善了放矿条件,降低了矿石贫化、损失率,提高了爆破质量、改善了大爆破安全条件,取得了较好的技术经济效果。
The author use the vacant- field and stage dilapidation mining method to substitute the mid- deep- bole stage dilapidation in production.It is a good way to reduce the dilution loss of mining and improve the safety and quality of blasting.
