文章指出,边界品位和最低平均工业品位对矿体的圈定影响甚大,而在实际工作中对其概念又有不明确、不统一之处。作者通过对一个稀有多金属矿床实例的分析,阐述了上述两项工业指标的概念及正确运用于合理圈定矿体的问题。
The article points out that the boundary grade and the lowest average industrial grade have a great influence on the delineation of ore bodies, but the concept of the boundary work is not clear or uniform in the actual work. Based on the analysis of an example of a rare polymetallic deposit, the author elaborates on the above two concepts of industrial indicators and the correct application of the method to properly delineate ore bodies.
