The article provides information on the development and testing of drugs to suppress dust on quarry roads. The rheological properties of the created powder suppressant technical solution based on starch and magnesium chloride were studied. It was found that as the amount of technical starch in the composition increases, its viscosity increases and the viscosity decreases with increasing temperature. It also contains information about the development of a special semi-industrial device for the preparation of an aqueous solution of technical starch and magnesium chloride, and the process of preparation of the composition solution. The created dust suppressants have been tested to suppress dust on the roads of the Muruntau quarry. Based on the results obtained, the amount of dust on the roads after spraying with the drug decreased from 15.6 mg/m3 to 2.6 mg/m3 after 5 days (120 hours) and the optimal composition of the composition was 6.0 mass. %. Technical starch and 7, 0 mass. % was found to contain magnesium chloride.
