摘　　要：在堆积型矿产勘查中“含矿率”是资源量估算重要的计算参数,实际勘查过程中存在“含矿率”单位不统一的问题,造成非地质勘查方面人员在查看勘查报告中存在困惑。本文主要通过不同的堆积型矿种“含矿率”进行比对分析和演算,表明“含矿率”单位用百分比(%)取代千克每立方米(kg/m^(3))具有可行和可操作性,更方便直观,并建议对矿产勘查规范中的“含矿率”单位进行更正。In the mineral exploration of accumulation deposit,"ore-bearig rate"is an important calculation parameter for resources estimation,and there is a problem that the"ore bearing rate"unit is not unified in the actual exploration process.It causes confusion for non-geological exploration personnel to review and check the exploration report.This paper mainly compares and analyzes the"mineral content"of different accumulation mineral resources,showing that it is feasible and operable to replace the"ore-bearing rate"unit with a percentage(%)instead of kg per cubic meter(kg/m^(3)).It is suggested that the unit of"ore bearing rate"should be corrected in the mineral exploration standard.
