Abstract. The purpose of this article is to clarify the hypothesis of mechanism of aggregative stability of the structured suspension dynamics, the essence of which consists in comparing the bond energy of the solid material particles in their coagulation structure and external energy of the fluid flow aimed to break this bond. In geotechnical systems, the key factors contributing to aggregate stability of the structured suspension transported through the pipelines, are: particle size, nature of solid material and its mineral inclusions, potential of the particle surface, ratio of total energy of the particles interaction in the fluid and energy flow.

Keywords: aggregate stability, energy flow, structured suspension.
