中文摘要:
      刚果(金)SICOMINES铜钴矿是一个铜金属量达千万吨的特大型铜钴矿床,如何保证矿产资源的充分利用是影响矿山经济效益和可持续发展的重要课题。文章阐述了矿体二次圈定在该矿山生产中的应用情况,并结合矿体产状较平缓、上下层矿体厚度变化不均匀的特点,采用了“分段取样”方法,对矿体二次圈定进行优化,有效提高了矿体圈定的精度,降低了矿石损失贫化率,也取得了显著经济效益。
英文摘要:
      The SICOMINES is an extra-large copper and cobalt deposit that copper metal reserves are about 10 million tons in D. R. Congo. It’s an important issue affecting economic benefits and sustainable development of mines how to make full use of mineral resources. The practical application of secondary delineation of ore bodies in SICOMINES Copper-Cobalt Deposit of D. R. Congo is introduced. The "subsection sampling" method is used to optimize the ore body secondary delineation, combining with the occurrence of ore bodies is gentle, and ore body thickness changes the characteristics of uneven, that improved the accuracy of ore body delineation,reduced the loss of ore dilution rate, made significant economic benefits.
