打開文本圖片集

摘要：紫金山銅礦Ⅺ號礦帶為高硫化型淺成中低溫熱液礦床，具有明顯的垂直礦化分帶特征。該礦帶經(jīng)過基建勘探、生產(chǎn)勘探、二次圈礦工作以后，發(fā)現(xiàn)礦體厚度和品位均有較大的變化。在總結(jié)該礦帶地質(zhì)特征的基礎上，通過對比礦體形態(tài)、儲量在基建勘探、生產(chǎn)勘探、二次圈礦的變化，探討勘探類型劃分和勘探工程網(wǎng)度選擇的合理性。

關鍵詞：探采對比；生產(chǎn)勘探；二次圈礦；工程間距

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
