摘要：紫金山铜矿Ⅺ号矿带为高硫化型浅成中低温热液矿床，具有明显的垂直矿化分带特征。该矿带经过基建勘探、生产勘探、二次圈矿工作以后，发现矿体厚度和品位均有较大的变化。在总结该矿带地质特征的基础上，通过对比矿体形态、储量在基建勘探、生产勘探、二次圈矿的变化，探讨勘探类型划分和勘探工程网度选择的合理性。

Abstract： The Zijinshan Ⅺ Copper is a high sulfide shallow to medium low temperature hydrothermal deposit with obvious vertical mineralization zoning characteristics. After infrastructure exploration， production exploration， and secondary ring mining work， it was found that there were significant changes in the thickness and grade of the ore body in this mining zone. On the basis of summarizing the geological characteristics of the ore belt， this paper explores the rationality of exploration type classification and exploration engineering network selection by comparing the changes in ore body morphology and reserves in infrastructure exploration， production exploration， and secondary circle mining.

Keywords： exploration and mining comparison; production exploration; secondary mining circle; engineering spacing
