摘要
获各琦铅锌矿体具有形态变化复杂、品位低且矿化极不均匀、构造发育等特点,因此在采准工程实施的基础上进行矿体的二次圈定十分必要。详细阐述了二次圈定工作的方法与步骤,二次圈定前、后矿体储量、品位以及形态的变化。结果表明,二次圈定可以有效降低生产成本,深刻认识矿体形态,对指导生产具有重要应用价值。
Lead-zinc orebody in Huogeqi have features like shape change complicatedly, lower grade and ununiform mineralization, structural development and so on, so it is very necessary to take second termination on orebody on the basis of mining preparation project implementation. Detailed description about the methods and steps of the second termination is made, as well as the change of orehody reserves, grade and shape before and after the second termination. The second termination can reduce production cost effectively, which makes us get profound understanding about the orebody shape with very important application values for guiding production.
