In Zhou et al.'s study, a surfactant made with sodium dodecylbenzene sulfonate (SDBS) was used to suppress coal dust at a blasting driving face in an underground coal mine (Zhou et al., 2018). The results showed that the surfactant could reduce 86.45% of the total dust, compared to 30.22% efficiency only use water.Web
