| 摘 要： | 本文认为计算金矿床品位、厚度变化系数的样品为参加储量计算的平衡表内各级储量的全部基本分析样品,计算的顺序是先矿体后全区,应以单排样参加计算,厚度和品位变化系数的样品必须吻合,应在未处理特高品位时计算。用砂钻勘探的砂金矿床应以单工程的混合砂厚度、混合砂品位进行计算。

| Abstract: | The author of this paper believes that the samples used for calculating the variation coefficients in grade and thickness of gold deposits should be all the general samples analysed and taken into account in the calculation of reserves of each class in the reserve balance sheet, and the order of calculation should be the orebody first and then the whole ore district, and the samples to be calculated should be the prospecting lines. The samples used in calculating thickness variation coefficient shouldcoincide with those for calculating grabe variation coefficient. All these should be calculated before treating of erratic high-grade. For the placer gold deposits prospected through Banka drilling. the single hole composite thickness and grade should be applied. |
