矿石平均品位的计算方法有算术平均法和加权平均法。兩种不同方法的采用是取决于矿石品位的变化程度,以及品位变化与矿体厚度(采样長度)的依賴关系。“有用成分均匀分佈并且品位与矿体厚度間没有依賴关系,以及在块段周圍取样分佈十分均匀的情况下,块段平均品位及平均厚度可以按算术平均法确定。当品位与厚度间存在依賴关系时,平均品位則以厚度加权平均法确定”。H·B·沃罗多蒙諾夫研
Average ore grade calculation methods are arithmetic mean and weighted average method. The use of two different methods depends on the degree of ore grade change and on the dependence of grade changes on ore body thickness (sample length). “The average composition and average thickness of the blocks can be determined arithmetically, if the useful components are evenly distributed and there is no dependency between the grade and the thickness of the ore body and where the sampling distribution is very uniform around the blocks. When the grade and thickness are dependent Relationship, the average grade thickness is determined by the weighted average method. ” H · B · Vorodoreanov research
