摘　　要：为了促进地浸铀资源的充分利用,统计分析了内蒙古某地浸铀矿山研究区内的矿段厚度、过滤器长度和矿层有效厚度,采用三维矿业软件构建矿体地质模型与开采模型,通过三维实体的可视化对比,精准掌握了浸采范围外“残难矿体”的位置,并对其进行了剩余资源量估算,结果表明剩余资源量可观,有待进一步研究。应用价格法测算矿床的经济指标,对矿床进行技术经济评价,将经济平米铀量作为阈值约束浸采范围外的“残难矿体”资源模型并生成经济块段模型;采用距离幂次反比法对经济块段模型进行资源量估算,得到平米铀量在经济指标之上的资源量。通过研究,掌握了研究区内纵向浸采范围外“残难矿体”的精确位置、剩余资源量和经济性,实现了对地浸开采矿山剩余资源量的经济评价。In order to promote the full utilization of in-situ leaching uranium resources,statistical analysis was conducted on the thickness of ore bodies,filter length,and effective thickness of ore layers in a research area of an in-situ leaching uranium mine in Inner Mongolia.The three-dimensional mining software was used to construct a geological model and mining model of the ore body.Through visual comparison of three-dimensional entities,the location of the"residual difficult ore body"outside the leaching range was accurately grasped,and the remaining resource amount was estimated.The results show that the remaining resource amount was considerable and needed further research.Using the price method to calculate the economic indicators of the deposit,conducting a technical and economic evaluation of the deposit,using the calculated economic uranium per square meter as a threshold to constrain the resource model of the"residual difficult ore body"outside the leaching range,and generating an economic block model.Using the inverse distance power method to estimate the resource quantity of the economic block model,the resource quantity of the uranium per square meter above the economic indicators is estimated.Through research,the precise location,remaining resources,and economic viability of"residual difficult ore bodies"outside the vertical leaching range within the research area have been mastered,achieving economic evaluation of the remaining resources of in-situ leaching mines.
