| 摘 要： | SD法创立于20世纪80年代初,它是一种以SD动态分维几何学为理论,以最佳结构地质变量为基础的储量计算方法;SD法适于不同矿种及矿产勘查开采各个阶段,是储量计算、矿业评估评审的一种工具;它创造性的提出精度概念,对所计算的结果以及施工工程数进行预测;通过对SD法与传统法在单工程矿体圈定、计算范围、品位厚度计算方式、特高品位处理及图件输出等方面的对比,对SD法计算系统的优点与不足进行了说明,实践证明,SD法能较好的适用于金矿勘查区的储量计算.

| Abstract: | SD method was established in the beginning of 1980's.It is based on dynamic fractal geometry and structural geologic variable theory.The method can be applied in different type deposits and every stage from ore surveying to exploration,and is a tool for reserves calculation and assessment.Precision in SD method can forecast result of reserves calculation and number of construction work.By comparing SD method and traditional method in orebody outline of single engineering,calculation limits,calculating pattern of grade,managing higher grade and diagram output,advantage and disadvantage of SD method calculation system are explained.It is proved that SD reserves calculation system can be used in gold exploration areas. |
