Abstract: The article considers the relevance of the problem of dust suppression at coal mines and enterprises of the Kemerovo region-Kuzbass. A brief review of methods of dust control using wetting solutions is carried out. It is established that, when working combines in coal mines, the means of dedusting used do not provide a reduction in the dust content of the air to the regulatory requirements. An example of the development of a complex solution of a highly effective coal dust wetting agent is given. The effectiveness of the wetting agent was evaluated by the method of membranous flotation. As a result of the work, a wetting agent solution was developed, which has a shorter coal dust deposition time compared to existing analogues.

Key words: wetting agent dust suppression coal dust membranous flotation method dust suppression study
