Abstract
The efficiency of uranium mining by the in-situ leaching method depends on the opening scheme choice at the design stage of a production unit. An information system for the design and optimization of opening schemes for technological units of an underground leaching field is presented. Opening schemes are built on the basis of geological and mathematical models of deposits, including the distribution of effective capacity and productivity. The system allows the construction of in-line, cellular, and adaptive opening schemes, in accordance with the specified parameters. The construction can be performed in manual or automatic modes. For the created opening schemes, the geotechnological parameters of the operational units, the predicted geotechnological and financial and economic indicators of mining for a given degree of uranium extraction are calculated. The unit parameters are calculated on the basis of the spatial distributions of physical quantities. Adequate mathematical models are used to calculate predictive geotechnological and financial and economic indicators. The constructed opening schemes can be optimized in the manual or automatic mode based on the use of the gradient descent method. During optimization, the block can be rotated, moved, or resized. During optimization, various objective functions, as well as their linear combination, can be used. The system also allows customizing and generating the report documentation. The system consists of five modules that interact with the project base, geological, and technological databases. Interaction with the databases is carried out through SQL queries. The use of the system will allow automating the process of selecting the most effective opening schemes, improving the quality of report documents, and increasing the accuracy of forecasting.
