Examples are given of the PGO system scheme with a dispenser for a liquid wetting agent, a scheme for installing a PGO in a coal storehouse, and a schematic diagram of a pendant mobile PGO system for spraying a dust stopping screen. Tests of the PGO system have proved its effectiveness. Correct installation and adjustment in premises, sites of overloading and galleries increases the effect of dust suppression to 98%, and in open areas to 80%. In combination with the existing installation "Wind barrier", the efficiency of the PGO system in open areas can reach 90%. The article notes that to actively introduce such systems into the production cycle, it is necessary to revise the regulatory framework in the field of operating rules for thermal power plants.
