AP19676743 — Development of methods for calculating the scheme of unbalanced solutions, operating modes of a geotechnological blocks and the creation of a geotechnological information system for efficient recovering by In-Situ Leaching
Purpose: The aim of the project is to develop a geotechnological information system, as well as methods for determining the scheme of unbalances for the distribution of process solutions over cells and the operating modes of a geotechnological block to increase the efficiency of mining mineral deposits via In-Situ Leaching.
Relevance: During the extraction of uranium by the method of In-Situ Leaching (ISL), as a result of the imbalance of solutions, stagnant zones are formed, which are not covered by leaching solution, and as a result, the extraction of the mineral decreases. During the implementation of the project, the executors will propose methods for calculating the unbalance scheme and a method for ensuring the balance of solutions in cells and blocks for efficient acidification of the block and extraction of uranium without additional financial costs. The proposed methods will also help reduce the spreading of solutions outside the block boundaries and will be implemented as a geotechnological information system with a convenient user interface and visualizer.

Results obtained: Within the research project, a comprehensive analysis of factors affecting local imbalance of technological solutions in in-situ leaching was carried out, identifying key hydrodynamic and geological parameters governing flow distribution. A method for detecting cell-based imbalance schemes was developed, enabling more accurate assessment of inter-well interactions. Reactive transport modeling and comparative evaluation of solution distribution methods were performed, leading to the identification of the most effective approaches, including the distance-square method. A geotechnological information system with 2D/3D visualization (OpenGL, WebGL) and computational implementation in C# was developed. The proposed solutions were tested and validated, demonstrating their effectiveness in optimizing injection regimes and improving resource recovery. The obtained results are of practical significance and suitable for industrial implementation.
