Numerical Modeling of ORE Body and Development Hydrodynamic Models of in-Situ Leaching Process

Abstract

the article proves the urgency of studying the models of the uranium mining process by the method of underground leaching, which will allow to evaluate the dynamics of the technological process. More and more attention is paid to the modeling of the process of underground leaching (ISL), with the aim of solving the problems of raising the effectiveness of the process under consideration. The problems of extraction of underground leaching are described, the current state and description of the technology, connection with management problems is very actual development of new systems using the simulation results of the ISL process in the control loop. The article considers that there is an optimal pressure on the pumping wells according to the chosen criterion. Models of searching for the solution of the required flow rate for a quench well providing the maximum productivity of the solution at the outlet are constructed. In the paper, the tasks of determining the initial hydrodynamic parameters of wells and seams after conducting special investigations of wells with the use of deep instruments and information measuring instruments are solved.
