摘　　要：文章简述了SD法在寨上金矿北矿段的数据准备和储量计算过程,得出了可靠的储量成果,与传统储量计算结果进行了对比,得出了SD法金资源量结果减少,而矿石量却远大于传统方法的结论。从单工程圈矿差异、风暴品位处理、矿体边界推定和矿体品位厚度计算方法4个方面分析了存在差异的原因。运用SD软件系统对各矿体资源量的可靠性进行了评定,并进行了工程控制预测。It was summarized that SD method data preparation and the calculation of reserves process in this paper,the authors have obtained the reliable reserves achievement, on the contrast with the tradition calculation of reserves result, obtained conclusion that the SD method gold amount of resources result to reduce,but the ore quantity actually far was bigger than the conventional method. It was analyzed that the existence difference reason from a single engineering mine circle difference,storm grade,ore boundary treatment, presumption of ore grade and thickness calculation method four aspects, and the evaluation using the SD software system to various ore bodies＇ resources reliability has been carried on the engineering control forecast.
