摘　　要：赤柏松矿区分布几十个基性-超基性岩体,Ⅰ号岩体是矿区规模最大的岩体,长达4 950 m,1971在Ⅰ号岩体的北端发现地质储量为大型的铜镍矿床,2013年又进一步的在地下100 m标高向南部深部进一步的进行深部勘探。经过两期勘探和多年开采,积累了大量的地质信息。通过利用3Dmine矿业软件,建立钻孔和坑道数据库。依据Ⅰ号岩体为岩浆深部分异,多期次脉动侵入成岩成矿的原理,对岩体、主要岩相、矿体、截断岩体矿体的闪长岩脉建立三维模型,结合Ⅰ号岩体岩相矿化特征,通过分析、研究和预测,确定深部具有进一步勘探价值的靶区。The distribution of dozens of mafic-ultramafic bodies in yew mining area,the No.1 rock mass is the largest rock mass there,and the strike length 4 950m.A large copper-nickel deposit at the northern end of the No.1 rock mass was found in 1971,and further deep exploration in underground 100m level to the deep part of the south in 2013.After two period of exploration and many years of mining,a lot of geological information has been accumulated.Through the use of 3D mine mining software,drilling and tunneling database was established.According to deep partial differentiation of magma of No.1 rock mass,the principle of multi stage pulsation invading into diagenetic mineralization,the threedimensional model of rock mass,main lithofacies,ore bodies and diorite veins truncated rock body are established.Combining lithofacies mineralization characteristics of No.1 rock mass,the target area with further exploration value in the deep part is determined by analysis,research and prediction.
