Abstract:

In order to clarify the design principles, proportions, mechanism, and dust suppression effects of various types of mine dust suppressants, the research status of dust suppressants for underground and open-pit mines was summarized. The types of raw materials and dust suppression effect of the wetting dust suppressants and environmentally friendly adhesive dust suppressants were studied. The results show that the research on wetting dust suppressants is the key for dust suppressants for underground mines, including the physical and chemical essence of coal dust wettability, as well as the dust suppression effect and micro mechanism of different wetting dust suppressants. The consolidation performance of adhesive dust suppressants used in open-pit mines is the most important. The action principle of the new environmentally friendly dust suppressants mainly involves the dust suppression effect under natural polymer aggregation, microbial adhesion, and biomass material bonding. In view of the significant differences in the effectiveness and poor universality of various dust suppressants, future research needs to focus on refined dust suppressant research and development, standard dust suppressant performance tests, and theoretically guided research and development methods of dust suppressants.

Key words: dust suppressant, wettability, consolidation performance, mechanism, environmental protection
