| Abstract: | To address the critical issue of particulate matter emitted from mining operations, which poses a significant risk to human health, production safety, and the environment, a novel dust suppressant based on xanthan gum (XTG) as a coalescing agent was introduced in this study. The formulation innovatively combines anionic surfactants SDS (Sodium dodecyl sulfate) and SDBS (Sodium dodecyl benzene sulfonate) as well as nonionic surfactants OP-10, Tween-20 (Polyoxyethylene anhydrous sorbitan monolaurate) and Tween-80 (Polyoxyethylene anhydrous sorbitan monooleate) with 0.05% XTG to enhance the wettability of the solution. Considering the economy and practicality, 0.05% OP-10 + 0.05% XTG (M-OX) was finally selected as the optimal dust suppressant formulation. Through a series of experiments, including surface tension, contact angle, sedimentation, pH value, water retention, and wind erosion resistance tests, we proved that M-OX, with a pH value of 8.03, has the least impact on the environment, has better water retention, and has a significant dust suppression effect. The curing layer formed by M-OX can adapt to complex weather, maintains its integrity after rain and wind erosion, and exhibits excellent rain and wind erosion resistance. This study provides an environmentally friendly and effective dust suppression solution for surface coal mines with significant social and economic benefits. [ABSTRACT FROM AUTHOR] |
