鸡笼山Cu-Au-Mo多金属矿已采中段漏采矿体勘探思路探讨

鸡笼山Cu-Au-Mo多金属矿床是鄂东南矿集区丰山矿田中一个典型的夕卡岩型、斑岩型铜金钼多金属矿,矿体主要赋存于燕山期中酸性侵入岩与大冶组碳酸盐岩建造的接触带及附近,受地层、构造、岩浆岩的联合控制。文章讨论了矿山已采中段中构造错失矿体、边部矿体及盲矿体等漏采矿体的勘探思路、方法及实践,运用成矿规律分析-坑道地质调查-采样分析-重点靶区圈定-坑内钻探验证的工作程序得以实施。

Discussion on exploring the missing ore bodies in the exploited levels of Jilongshan Cu-Au-Mo polymetallic mine

Jilongshan Cu-Au-Mo polymetallic deposit is a typical skarn-porphyry type deposit in Fengshan ore field in southeast Hubei province.The ore bodies occur mainly in or around the contact zone between Yanshanian intermediate-acid intrusive rocks and limestones of Daye formation,and are controlled by combination of the formation,structure and magmatic rocks.This paper discusses the exploration strategies,methods and practice about ore bodies that are displaced by faulting or at depth and surroundings of the ore bodies but missed by mining.The strategies was carried out in sequence of metallogenic regularity analysis,tunnel geological survey,sampling and analysis,key target delineation,drilling verification.
