Solid coal dust suppressant

The invention relates to the technical field of dust control, in particular to a solid coal dust suppressant which comprises a liquid component and a solid powder component. The liquid component comprises the following components in parts by mass: 30-65 parts of a crusting agent and 45-65 parts of an anti-freezing agent; the solid powder comprises the following components in parts by mass: 3-5 parts of a dispersing agent, 2-3 parts of a corrosion inhibitor, 1 part of a surfactant and 60-80 parts of solid sugar. According to the invention, pulverized coal can be effectively adsorbed, so that the pulverized coal is not easy to blow away, and a formed curing shell is of a net-shaped structure, has good permeability while fixing and locking the dust, is convenient for heat dissipation among the pulverized coal in a coal transportation process, and does not affect later use and combustion of the coal at the same time. The problems that an existing solid dust suppressant is difficult to dissolve, a spraying pipelin
