摘要
铅锌矿所采出原矿的Pb、Zn品位在出矿随机取样分析时所得到的检测结果的统计分布状况同时也反映了矿产资源在一定的地质条件下所生成的地质原矿金属品位的分布。根据统计资料对原矿的Pb、Zn品位分布状况进行研究,目的就是找出其分布规律,以建立其分布的概率密度函数,结合探矿时矿体的资料科学地计算出原矿Pb、Zn品位分布区间的概率。以便更准确地推断矿产资料储有量。
The determination results from the analysis of Pb and Zn in the run - of mine ore indicate the geologic grade distribution of the ore resource underground. Based on the statistic data, the distribution of Pb and Zn grade in the ran - of - mine ore has been studied so as to find the distribution rule, build the probability density function of its distribution, calculate the probability of Pb and Zn grade distribution of run - of - mine ore with reference of ore body from exploring, and the reserves of minerals resource can be deduced more accurately.
