Outline
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.
