To the question of parameter optimization of hydraulic transportation technology

Abstract

Background. The selection of rational schemes for the technology of hydraulic transportation of rock mass requires optimization of the main parameters of this technology. A large number of factors determining the efficiency of hydraulic transportation hamper the formalization of relationships of the main transportation processes both between themselves and other mining and processing processes.Aim. To identify specific features of the main processes in hydraulic transportation technology, to establish the factors and parameters that determine their optimal operation, and to propose an optimization tool for both individual links and the entire chain of hydraulic transportation of rock mass.Materials and methods. The problem of parameter optimization of hydraulic transportation of mineral raw materials is solved based on the integral characteristics of the pressure movement of ore and rock hydraulic mixtures. These characteristics were previously obtained empirically or theoretically by the authors of the present paper and other researchers at various mining companies.Results. Among the variety of factors determining the efficiency of hydraulic transportation, the size of the transported piece (ore, rock, coal) was found to play the major role. At the same time, the nature of changes in economic expenditures and results of evaluating the effectiveness of hydraulic transportation technology will always relate to a specific field, the accepted technological scheme, and the equipment used.Conclusion. The problem of parameter optimization of hydraulic transportation processes can be solved using digital twin technology. This technology can be used to address the issues of managing complicated technological processes, as the same time allowing timely adjustments to the modes and parameters of operational processes both on individual production lines and at the enterprise as a whole.
