摘要
通过详细地叙述浅孔留矿法在甲乌拉铅锌矿开采过程中的应用,指出对于矿岩稳固、矿岩界限明显、倾角变化不大的急倾斜薄矿脉,采用浅孔凿岩,"之"字型布孔,不耦合装药和微差爆破等技术和措施,可以大幅度提高矿块生产能力、生产效率,降低采矿成本,提高矿山综合效益。
This article describes the application of Short-hole shrinkage method in Jiawula lead-zinc deposit in detail. It points out that the employment of Shallow hole drilling, Z-shaped pattern of laying blast holes, uncoupled charging and microsecond blast is capable of improving productivity and efficiency of ore block, reducing mining cost,and increasing economic profits in the mining of steep dip and narrow vein, of which the ore rock is moderately stable, the demarcation line between rock and ore is clear and the change of dip angle is not so great.
