萨热克铜矿DIMINE三维地质建模及储量估算

Three Dimensional Geological Model and Reserve Estimation of Sareke Copper Mine on the Basis of DIMINE

为了探清萨热克铜矿开采后在矿体形态、储量、品位的变化情况，采用 DIMINE 软件进行矿体三维地质建模及储量估算。结果表明，DIMINE 能有效、准确地实现矿山地表模型、矿体模型及井下工程的可视化。萨热克铜矿可按层状位置分为1～5号矿体，2790～2600 m 标高区间矿石储量1606.6万 t，Cu 平均品位1.08％。DI-MINE 矿体模型储量估算结果与钻孔工程验证情况基本一致。

To investigate the evolutions of deposit regularity,reserve and mineral grade of Sareke copper mine during mining,software DIMINE was introduced to establish the three dimensional geological models and reserve estimations.The results showed that DIMINE successfully and precisely realized the visual-ization of surface model,deposit models and underground engineering.The metallogenetic zones were di-vided to five deposits according to stratiform spatial locations.The reserve reached to 16.066 million tons in the altitude range of 2 790 m and 2 600 m,and the average copper grade was 1.08%.Additionally, the reserve estimations by DIMINE were consistent with the results verified by drilling engineering.
