金厂金矿床的勘探是以钻探为主要手段,钻孔样品中金含量涨落很大。为了验证钻探取样的可靠性,选择了6个已施工钻孔,在原孔位施工6个浅井,并在浅井的不同侧壁用不同方法按原钻孔的取样长度和深度取了对应样。从金含量分析结果看,浅井中不同壁和不同方法采样之间、浅井采样平均和钻孔采样之间的表观差异很大,不能直接判定钻孔取样的可靠性。为了解决这个问题,我们进行了均值检验。
The exploration of the Jinchang Gold Deposit is based on drilling, and the gold content in the drilling samples fluctuates greatly. In order to verify the reliability of drilling sampling, six constructed boreholes were selected and six shallow wells were drilled in the original borehole. Corresponding samples were taken from different sidewalls of the shallow well according to the sampling length and depth of the original boreholes. From the results of gold content analysis, the apparent difference between the average sampling of shallow wells and the sampling of boreholes varies greatly among shallow walls and different sampling methods, and can not directly determine the reliability of drilling sampling. In order to solve this problem, we conducted a mean test.
