摘　　要：在对指示克里格估值进行深入研究的基础上,确定指示概率模型进行矿化带边界确定的基本方案.针对某铜矿区,采用指示概率模型确定该矿化带边界,并利用普通克里格方法对矿体进行估值.通过将估值结果与人工矿体圈定进行储量估值的结果进行对比研究,对指示克里格法的矿体圈定进行了验证.Based on the study of indicator Kriging method, the program by using indicator Kriging probability model to define the ore body domains was determined. Taking for example one copper mine, this domain was defined by indicator Kriging probability model, and the mineral deposit model was estimated by ordinary kriging method. Then, Indicator Kriging method is examined strictly by comparing the valuation results to reserves results of artificially delineate orebody.
