摘　　要：我国低品位的多金属矿床较多,利用论证的综合品位指标圈连矿体,对矿体的形态、规模、资源储量规模及矿床开发的经济效益潜力评价都有重要影响。分析了矿床工业指标的构成要素及其选取条件,提出了不同品位指标的测算公式。选择广西南丹矿黑水沟—大树脚矿段锌多金属矿为案例,提出多套工业指标方案,论证了边界品位、盈亏平衡品位等具体的工业指标,圈出了矿体,估算了矿产资源量。通过对比分析可以看出,只有全面考虑矿体特征、选矿回收率、开采经济效益等因素,确定合理的最低综合品位指标,才能保证充分开发矿产资源。There are many low-grade polymetallic deposits in our country.It is important to use the comprehensive grade index to circle the ore body,which has an impact on the form,scale,resource re⁃serve scale of the ore body and the evaluation of the economic benefit potential of the ore development.This paper analyzes the components and selection conditions of industrial indexes of ore deposits,and puts for⁃ward the calculation formulas of different grade indexes.Taking the zinc polymetallic ore in Heishuigou-Dashujiao section of Guangxi Nandan Mine as an example,this paper puts forward several sets of industrial index schemes,demonstrates the specific industrial indexes such as boundary grade and break even grade,delineates the ore body and estimates the mineral resources.Through comparative analysis,it can be seen that only by comprehensively considering the characteristics of ore bodies,recovery rate of mineral process⁃ing,economic benefits of mining and other factors,and determining a reasonable minimum comprehensive grade index,can we ensure the full development of mineral resources could being ensured.

关 键 词：矿床工业指标 边界品位 最低工业品位 最低综合工业品位 矿床平均品位
