Abstract. The purpose of the publication is to create methodological foundations for determining the critical hydraulic transport speed by the values of hydraulic slope, flow rate and density of the hydraulic compoud and to assess, on the basis of these data, the current characteristics of the hydraulic compoud solid phase particles. To achieve this goal, the following research methods were used: generalisation of the known methods for calculating hydraulic transport parameters and mathematical processing of data obtained from the data of the services of mechanics, power engineering, control of measuring equipment as well as real-time monitoring. A historical review of the introduction of systems for operational monitoring of flow parameters at domestic hydraulic transport complexes of mining enterprises was carried out. The technical means of controlling and recording the flow rate and pressure of the hydraulic compoud, methods for determining its density and cargo flow were analysed. This made it possible to substantiate the parameters that can be used to achieve the research goal of determining the parameters of the transported material based on operational measurements. The results of the study are the establishment of the dependence of generalised values of the parameters of solid particles of the transported material on the hydraulic characteristics of the hydraulic compoud flow, taking into account the characteristics of the pipeline and the characteristics of the transported material. The obtained formulas make it possible to determine the current generalised values of the parameters of solid particles of the transported material based on the data of monitoring and operational control systems of hydraulic transport parameters, taking into account the characteristics of the pipeline and the characteristics of the transported material. These dependencies can be solved in relation to the density of the transported material particles or their diameter, depending on the mining-geological or mining-technological conditions of open-pit mining, which allows to increase the reliability and efficiency of the hydraulic transport complex by timely changing the parameters and operating modes. The scientific novelty of the research results is to determine the dependence of the product of the diameter and Archimedes' parameter of the particles of the solid phase of the hydraulic compoud on the concentration of the hydraulic compoud and its average speed, hydraulic slope of the hydraulic compoud and liquid.
Keywords: critical hydraulic transport speed, parameters of the transported material, hydraulic slope of the hydraulic compound, concentration of the hydraulic compound.
