摘　　要：南京九华山铜矿区仙人桥矿段经部分开采后发现,矿体形态、矿床储量等方面与矿区原详查报告存在较大差异。结合矿区开采及勘探资料,分析了矿区地质特征、矿体地质特征、围岩特征,并进行了探采对比分析。研究表明:(1)矿区构造特别是断裂构造控制着仙人桥矿段的矿体形态;(2)矿区围岩类型与岩浆岩的接触带影响着矿体的规模;(3)仙人桥矿段2#矿体成因主要受矿区F2压扭性断层控制,在与F2断层交叉的张性断裂部位往往富集规模较大的囊状矿体。在上述分析的基础上,对矿区找矿方向进行了初步探讨,认为矿区除沿F2断层带进行找矿外,与F2断层相交的张性断裂也为较有利的找矿区段。上述分析对于区内进一步开展铜矿床找矿勘探及开采工作有一定的参考价值。The partial mining results of the Xianrenqiao ore section of Jiuhuashan copper mining ar- ea show that the big difference between the actual situations of ore-body shapes and deposit reserves and the results of the original detailed survey report of the mining area is existed. Combing with the actual mining and exploration results of the mining area, the geological characteristics of the mining area, geolog- ical characteristics of the ore-bodies, characteristics of surrounding rock are analyzed, and analysis and comparison of prospecting and mining of the Xianrenqiao ore section is also conducted. The study results show that：（~）the ore-bodies shapes is controlled by the structures especially the fracture structures of the mining area;（~）the ore-bodies scale is influenced by surrounding rock type and contact zone of magmatic rocks in the mining area;（~）the genesis of 2# ore-body of Xianrenqiao ore section is mainly controlled by F2 compressive shear fault, the large cystic ore-body is enriched in the cross position of F2 compressive shear fault and tensile fracture. Based on the above analysis results, the prospecting directions of the min- ing area are discussed preliminarily, it is show that, besides the F2 fault, the tensile fracture that is crossed with F2 fault is also the favorable prospecting section in the mining area. The above analysis results of Xianrenqiao ore section can provide some reference for the further prospecting of copper deposit in Jiuhua- shan copper mining area.
