摘　　要：贵州省贞丰县烂泥沟金矿(锦丰)作为一座生产多年的老矿山,矿区整体工作程度高,各种找矿手段已基本覆盖全区,找矿难度之大无异于大海捞针。如果没有找矿新思路的转变,很难实现锦丰矿区的找矿突破。在这种背景下,本次工作,以现有工程控制程度为基础,充分梳理了前期各类资料,创新性提出数学地质+空间成矿学综合找矿思路。秉持这一思路,通过野外及井下实地调查发现矿体赋存与褶皱关系密切,多发育在紧闭褶皱一翼或核部,并非仅仅受断裂构造控制,应为褶皱及断裂联合控制,并在新的找矿思路及现场调查的基础上,提出了靶区进行验证,将冗半矿段作为重点探矿区域。The Lannigou Gold Mine(Jinfeng)in Zhenfeng County,Guizhou Province,is an old mine that has been in production for many years.The overall level of work in the mining area is high,and various prospecting methods have basically covered the entire area.The difficulty of prospecting is as great as finding a needle in a haystack.It is difficult to achieve a breakthrough in mineral exploration in the Jinfeng mining area without a shift in new mining strategies.In this context,based on the existing engineering control level,this work fully sorted out various types of data in the early stage and innovatively proposed a comprehensive exploration approach of mathematical geology and spatial mineralization.Adhering to this idea,through field and underground investigations,it was found that the occurrence of ore bodies is closely related to folds,mostly developed on one wing or core of tightly closed folds,not only controlled by fault structures,but should be jointly controlled by folds and faults.Based on new exploration ideas and on-site investigations,target areas were proposed for verification,and redundant ore sections were identified as key exploration areas.
