拉拉铜矿露天开采贫化损失管理

Didution and Loss Management of Opening Pit Mining on the Lala Copper Mine

贫化率和损失率是评价矿山开采技术水平的重要指标。本文对拉拉铜矿露天矿山开采现状进行了简单的描述,结合露天矿山地质条件,开采技术条件和管理水平指出产生矿石贫化和损失的原因,从地质、采矿、测量三方面着手,通过加强地质资料完善,进行合理采矿设计和现场施工推进方向,提高现场管理水平等主要措施,从而降低矿石贫化率和损失率。

Dilution ratio and mining loss rate were to evaluate the technical level of an important indicator. The paper is brief description of the opening pit mine of Lala copper mine. The reasons of ore dilution and losses are pointed out about the opening pit mine geological conditions, the mining technical conditions and management level. It is from the geology, mining and measuring that through these main measures which are strengthening geological data improvement, reasonable mining design and site construction advancing direction and improving field management to reduce ore dilution rate and loss rate.
