Abstract

Purpose. Justification of hydraulic systems management methods of mining and metallurgical plants, taking into account indicators and comparative analysis and on the basis of pipelines rational parameters and slurry concentrates.. Methodology. Analysis of modern methods for assessing the efficiency of operation of hydraulic systems of enterprises in the mining and metallurgical industry allowed us to determine the promising directions for the use of various chemical reagents in order to reduce hydraulic resistance during transportation of hydraulic mixtures in mineral processing technologies. Findings. The rational parameters of the operation of hydraulic systems of mining and smelting plants, namely: the diameter of the pipeline and the concentration of the slurry for a given amount of transportation to ensure a minimum of reduced costs for the evaluation period and taking into account the usage of chemicals which were used to improve the efficiency of pipeline transport. Originality. Based on the analysis of methods for assessing the effectiveness of mineral processing technologies. It is determined that the most rational in the totality of technologies to improve the efficiency and reliability of the hydrotransport complex is the use of polyethylene pipes, as well as additives to the carrier fluid of hydrodynamically active substances. Practical value. It consists in the improvement of methods for calculating rational parameters and modes of operation of hydraulic systems, allowing to determine the value of the velocity and concentration of the slurry, providing a minimum of reduced costs for the estimated period. These methods are adapted for the case of using polyethylene pipes, taking into account additives to the carrier fluid of hydrodynamically active substances, taking into account the reduction of reduced costs due to diagnosing the technical condition of the equipment, as well as allowing to optimize maintenance costs.
