摘　　要：按矿化特征将金川X矿区主矿体分为致密块状特富矿、海绵状富矿和浸染状贫矿。应用MicroMine软件对3类矿化体分别建立了数学模型,并应用距离平方反比法对模型单元块进行了镍、铜品位估值。通过分析和对比矿床数学模型900m至1300m不同水平剖面上的Ni、Cu品位及Ni/Cu比值的变化,得出在X矿区的中部西侧是一个Ni和Cu的矿化中心,并且向深部Cu的矿化强度高于Ni。According to mineralization characteristics, major orebedies of X Mining Segment in the Jinchuan deposit can be divided into three mineralization types, massive, net -texture and disseminated ores. Each type is modeled with Micromine software, and Ni and Cu contents are estimated using Distance Reverse separately. By comparing and analyzing Ni and Cu contents and Ni/Cu ratio of a series of block plans from 900m to 1300m level, it is concluded that a intensive Ni and Cu mineralizing centre occurs in the western - central part of X Mining Segment, and down to the deep, Cu mineralization can become more intensive than Ni.
