Abstract.  The subject of the research is the methods of calculating the parameters and flow regimes of structured suspensions, which have significant potential for substantial reduction in energy consumption and specific water consumption of all hydromechanization technologies used in mining enterprises. The main topic of the research is the stability of the suspension structure and uniform distribution of particles of its solid phase throughout the volume during pressure flow through the pipeline. The aim of the work is to establish dependencies on the relative radius that defines the flow area where the suspension structure is not destroyed, not only on the rheological characteristics of the suspension and hydraulic flow parameters but also on the gravitational and repulsive forces between the particles of the solid phase of the suspension, which have an ion-electrostatic and Van der Waals nature. It is established that forces having ion-electrostatic and Van der Waals nature lead to a decrease in the maximum value of the relative radius, at which the suspension structure is still preserved during its flow in the pipeline, since the addition that takes into account their influence is always positive and subtracted from the addition that takes into account the relationship between the initial tangential stress and the hydraulic frictional stress on the inner surface of the pipe. The range of existence of the addition that takes into account the influence of forces having ion-electrostatic and Van der Waals nature and the range of variation of its values аt different values of the parameter of the energy interaction of particles of the solid phase of the structured suspension are investigated. It is established that the dependence of this addition on the distance between particles of the solid phase of the suspension is maximum. The magnitude and coordinates of the maximum depend on the parameter of the energy interaction of the solid phase particles. It is established that with an increase in the value of the parameter of the energy particles interaction of the suspension solid phase, the maximum value of the addition decreases, and the coordinate of this maximum increases.
Keywords: structured suspension, radius of undeformed flow core, ion-electrostatic forces, pressure flow, pipeline.
