The paper presents the results of research and industrial tests of the effectiveness of the use of reagents for dust binding of dusty surfaces on the example of dry surfaces of tailings storage facilities of PJSC “InGZK” and PJSC “PivnGZK”. In the course of the research under contract No. 1205 dated 30.12.2021 between the Research Institute of Mining and Ore and PJSC "PivnGZK" from January 2022 until August 2022 two series of research on the properties of 16 reagents available on the market of Ukraine, which can be used for dust binding of dusting surfaces, were conducted, and a rating of reagents was formed according to the following indicators: stability of the protective layer; dust emission intensity; strength of the protective layer (ultrasonic method); the thickness of the protective layer; surface water absorption.
According to the results of laboratory studies, the binding process of finely dispersed dust particles, which actively participate in the general process of dust cloud formation in the conditions of dust formation of dry surfaces of tailings storage facilities, was substantiated, and a general rating of reagents based on the effectiveness of their use was formed.
