摘要
笔者提出一种用群孔对比来研究二组群孔是否属同一母体的砂金矿钻探质量检查方法。用此法检查钻探质量合格后,即可进一步计算储量误差。
The drilling quality control method for placer gold deposits is dealt with in this paper.Usuallythe repeated drill hole contrasting method is used,but the gold grade obtained varies greatly due tothe nugget effect of the deposit.Here we put forward a method by investigating two group of drillholes to see whether they are belonged to the same population or not for drilling quality checking.Ifthe drilling quality is proved to be up to standard,then we can go a step further to calculate the er-ror of the estimated ore reserves of the gold placer deposit.
