The addition of NVM has been shown to increase the viscosity of the system. The influence of carbon nanomaterials on the rheological characteristics of composite water-coal dispersions has been studied. It is shown that the increased reactivity of finely divided carbon with highly active newly formed contact interaction centers creates preconditions for the formation of a stable spatial structure under the action of a structural-mechanical stabilization factor. In the presence of NVM, the stability of the KVP increases significantly, but at the same time the effective viscosity increases. Evidence has been obtained that impurities of carbon micro- and nanoparticles with increased dispersion demonstrate the ability to form coagulation structures even when they are contained in the suspension in the amount of several percent. The peculiarities of the formation of a double electric layer on the surface of carbon particles in the presence of carbon nanomaterials are investigated. Additional desorption of ions from the surface of the particles of the dispersed phase activates electrostatic interactions between the particles. It can be noted that even without the use of chemical additives, the systems, which have undergone plasma-chemical activation with the formation of carbon microparticles, show a significant improvement in rheological properties.
