龙脖河铜矿龙达矿段地质特征及资源/储量估算

Resources / reserves estimation and geological characteristics in Longda ore section of Longbohe Copper Deposit

龙脖河铜矿龙达矿段Ⅲ1-4号矿群共有5个矿体。通过研究龙达矿段的地质特征,基本查明了Ⅲ1-4号矿群5个矿体的形态、产状、空间位置及厚度、品位的变化情况;基于地质块段法在探矿区范围内对Ⅲ1-4号矿群进行了资源/储量的估算,获得了5个铜矿体332+333总金属量18 559.57 t,为龙脖河铜矿今后的进一步资源开发规划提供了依据。

5 orebodies exist in No. 1 to 4 ore clusters of Longda Ore Section Ⅲ of Longbohe Copper Deposit. The paper studied geological characteristics in Longda ore section,and basically found out the morphology,occurrence status,spatial layout and the variance of thickness and grade of the 5 orebodies in No. 1 to 4 ore clusters of Ore SectionⅢ. Reserves estimation of No. 1 to 4 ore clusters in Section Ⅲ is carried out within the prospecting area based on the geological ore block method. The data show that the total metal reserve of 5 copper orebodies 332 ＋ 333 is 18 559. 57 t,providing basis for further resources development planning for Longbohe Copper Deposit.
