我们队工作的矿区是属于一种矿体均匀的矿床，因此由钻探所获得的岩心，全部都要取样分析。我们取样的规格，是按孔深每2公尺为一个样品，每个样品该取岩心的长度，受岩心获取率的影响，这是容易了解的。但在有上次残留岩心存在的情况下，一个样品取至某次提出岩心中的某一个位置，是直接与残留岩心有关的。目前我们钻探，残留岩心的现象普遍存在着，为了取样位置的准确以及矿体在柱状图中的位置更近于正确，我们对残留岩心的计算，作了一些研究，初步得到了一些方法，现在提出来供大家参考，有错误的地方，希望大家指正。
The mining area where our team works belongs to a deposit of uniform ore body, so the cores obtained from drilling are all sampled and analyzed. The specifications of our sampling are based on a hole depth of 2 meters for each sample, the length of each sample taken from the core, affected by the rate of core access, which is easy to understand. However, in the presence of the last remaining core, a sample taken to a particular location in the proposed core is directly related to the remaining core. At present, the phenomena of drilling and residual core are ubiquitous. In order to make the sampling location accurate and the ore body’s position in the histogram closer to the right, we made some research on the calculation of the residual core and obtained some preliminary methods. Proposed for your reference, there are mistakes, I hope you correct me.
