摘　　要：矿床工业指标是一个动态性指标,应随矿山开采技术经济条件变化而实时调整,南方离子型稀土矿开采主要采用原地浸矿工艺,该工艺开采成本低、环境污染小。结合某离子型稀土矿地质勘探实际情况,通过对不同工业指标圈定的矿体进行开采经济论证,确定合理的矿床开采工业指标,正确评价稀土资源的工业价值,提高矿产勘查和开发利用的经济效益和资源效益,对类似矿山具有借鉴意义。The industrial indicator is a dynamic index, which should be adjusted real-timely with the changes of mining technological and economic conditions. Southern ion-absorbed rare earth mines in south China often use in situ leaching process, which has the advantages of low cost and less environmental pollution. Combined with the actual situa- tion of geological exploration of an ion-absorbed rare earth mine, the mining economic demonstration is conducted through the boundary demarcation of the orebody with different industrial indicators, and the reasonable indicator is determined. The industrial value of rare earth resources is evaluated correctly, and the economic benefits and resource efficiency of the mineral exploration and exploitation are improved, which can provide reference for similar mines.
