地浸开采资源储量四维动态评价系统在某铀矿山的应用

Application of Four Dimensional Dynamic Evaluation System for In-situ Leaching Uranium Mine

以某地浸铀矿山为例,应用地浸开采资源储量四维动态评价系统(RDS系统)构建了三维矿体模型,模拟了在矿床详查、勘探和开采过程中矿体的变化过程,并对资源储量进行了估算。在此基础上实现了对资源储量的动态管理,分析了保有资源量变化的原因;开展了过滤器可视化快速识别布置,确定了过滤器放置位置和长度;并对抽注单元铀浓度进行测算,得到了边界铀浓度、边际铀浓度和经济铀浓度等技术经济指标。现场应用表明,RDS系统为地浸铀矿山的数字化建设和生产设计提供了高效的手段和平台。

Taking an in-situ leaching uranium mine as an example,four dimensional dynamic evaluation system of in-situ leaching resources and reserves(RDS system)was applied to construct the three-dimensional ore body,simulate the ore body change process in the process of detailed investigation,exploration and mining,and estimate the resource reserve.On this basis,the dynamic management of resource reserve was realized and the reasons for the change of the amount of retained resources were analyzed.The visual rapid identification and layout of the filter was carried out,and the placement position and length configuration of the filter were determined.The uranium concentration of pumping unit was calculated,the technical and economic indexes of boundary uranium concentration,marginal uranium concentration and economic uranium concentration were obtained.The application in in-situ leaching uranium mines shows that the RDS system provides an efficient means and platform for the digital construction and production design of in-situ leaching uranium mines.
