Study on wettability of water stemming for blasting dust adjusted by surfactants and inorganic salts

Royal Society Open Science
Water stemming is an efficient method of removing blasting dust by wetting. There is still a lack of methods for rapid optimization of water stemming components with high wettability. Herein, blasting dust was collected from a tunnel in Chongqing (China)
