摘要
堆浸取矿样很重要。在没有矿石品位检测手段的矿山，多数按Ｑ＝ｋｄ２的最小取矿样量方法取样。即使如此，取矿样量仍然很大。考虑到矿石粒度分布和矿石品位随粒度分布关系，文中运用随机变量分布离散程度中等精度测定结果的精度估计法，提出按矿石粒度分布确定最小取矿样量的新方法。
Ore sampling is very important in the heap leaching. For lack of the monitoring instruments to examine the ore grade, most of mines determine the minimal ore sampling quantity according to the formula Q=kd2. Even so, the sampling of quantity is still much. Considering the distribution of ore size and the relation of ore grade with it, using the accuracy estimation method of results of equal-accuracy in discrete extent of random variabls distribution, the authors proposed a new method of determining minimal ore sampling quantity according to the ore particle size.
