摘要
通过对工业品位应用和产生条件的分析，揭示了单工程或块段最低工业品位（ 文中简称工业品位）并非圈矿指标和储量分类的标准。提出了在技术条件允许的前提下，普查阶段的矿床最低工业品位是勘查各阶段划分储量类别的标准，质量介于边界品位与单工程或块段最低工业品位之间的、不能成为独立开发对象的储量部分属于表内储量。在现行储量计算方法下。
The application of industrial grade and its creating conditions indicate that the index of industrial grade does not represent the standard for delineation of orebodies and classification of reserves. It is suggested that as long as the technical conditions are acceptable, the industrial grade used in the reconnaissance stage can be used as a criterion for the classification of reserves during each stage of exploration. It is concluded that a part of reserves with grades between cut-off and industrial ones and being unable to be developed independently belongs to useable reserves. In the present situation, the cut-off is the reasonable index for delineation of orebodies.
