Abstract The problem of rational nature management in the field of mining of hydromineral raw materials requires the use of new technological solutions that ensure the environmental safety of operating the hydromineral base with increasing demands for hydromineral raw materials. Using the principles and methods of systems with distributed parameters, it is possible (with the given fields of the depression funnel reflecting the desired technological mode of operation of the mineral water field) to increase the flow rate. The desired process mode is provided by the system for controlling the parameters of the hydro-lithospheric process. The input impact on the control object (hydro-lithospheric process) is the flow rates of producing wells. The exit function is to lower the level in the zones where the well is located. The problem of choosing an actuator (determining the number of production wells and their location) is one of the central ones in solving the design problem of distributed control systems for hydro-lithospheric processes. Production wells have a significant impact on lowering the level in the areas of their location. Mathematically, this effect can be described using the Jacob ratio, using the values of the hydraulic parameters of the aquifers. Determining these parameters is a complex and expensive task. The article discusses the technology of designing a single production well control system and the transition to distributed control systems for hydro-lithospheric processes. The structure and methodology for calculating the parameters of the approximating link describing the change in the level of the spatial coordinate is given. To determine the parameters of the considered link, either experimental studies or numerical modeling of the control object are carried out. Using an approximation link, the article discusses the solution to the problem of selecting the number of producing wells based on ensuring maximum income for a selected field life. At the same time, the same level of reduction was set in the zones of production wells, ensuring the specified technological mode of field operation, as well as the geometric boundaries of the wells. Of course, the choice of the number of producing wells can be made on the basis of other criteria. Designing distributed control systems for a set of production wells is discussed in the literature on the synthesis of systems with distributed parameters.
