摘　　要：广西大厂是世界著名的锡多金属成矿区,矿田内生产规模最大的是铜坑矿,矿床空间分带特征明显,从地表到深部赋存有北东向裂隙脉型、细脉带型、细脉交代型(91#)、网脉浸染型(92#)和矽卡岩型锌铜矿体。在矿山生产实践中,根据物探、化探、坑探及钻探等成矿信息分析,认为铜坑矿深边部具有良好的成矿条件,对找矿靶区进行了部分工程验证,表明铜坑矿找矿潜力巨大,实践证明在老矿山周边找矿是增加储量资源快速有效的途径。Dachang is a well-known Tiwpolymetallic mine field in the world. Tongkeng Mine is the largest pro- duction scale mine with obvious spatial zonation. There are north east fissure-vein type, veinlet-belt type, veinlet - metasomatic type（No. 91）, stockwork-disseminated type（No. 92） and skarn type zinc-copper orebody from the sur- face to depth. In production practice, according to the analysis of metallogenic information from geophysical pros- pecting, geochemical prospecting, pitting and drilling, it is suggested that the depth part and margin area of Tongkeng Mine has good metallogenic condition. The verification of some engineering in the mine prospecting target indicates that Tongkeng mine has huge Ore-searching Potential. The practices show that prospecting in surrounding old mines is a fast and effective way to increase reserves resources.
