Abstract. Significant problems for local geotechnical systems are reducing of energy intensity of the mineral transportation and resource conservation. These aspects must be taken into account when elaborating methods for improving technological effectiveness of structured suspension usage. Purpose of process of structured suspension preparation is to obtain a mechanical mixture with a predetermined concentration and physical and rheological properties from particulate solid material and fluid. Objective of this work was to validate rheological parameters of structured suspensions which ensured reliable delivery of solids to the consumer in the required amount by available pumps through existing pipelines, and this problem was solved The offered method allows to determine such suspension concentration value, which ensures coincidence of concerned system operating point with the scheduled feeding value.

Keywords: structured suspension, rheological characteristics, pressure hydrotransport, mathematical simulation.
