The efficiency of mining hydromechanized roof supports is largely determined by the quality of working fluids – emulsions. The use of water-soluble imported emulsol for their preparation is currently constrained by the cost of the latter and difficulties in logistical terms, especially given the fact, that a very large number of mining enterprises have old, heavily worn rock supports with increased emulsion consumption. To solve this problem, a flow modulating dispersant was developed, the principle of which is based on cavitation for intensive mixing of water and emulsol. A stand was built with an experimental dispersant and an emulsion was prepared, consisting by volume of 98 % water and 2 % domestic emulsol. An analysis of the obtained working fluid, carried out using an electron microscope, showed, that this emulsion has a 30…50 % higher dispersion, than traditional emulsions, prepared using known hydromechanical dispersants.
