Preparation and performance characterization of a composite dust suppressant for preventing secondary dust in underground mine roadways

The purpose of this study is to prepare an environmentally friendly composite dust suppressant that can be used to wet the dust deposited in underground mine roadways, where it can effectively prevent the occurrence of dust. The dust suppressant is prepared by using starch as the raw material and methyl methacrylate and acrylamide as monomers, followed by mixing with a surfactant. FTIR, XRD and SEM are employed to compare the changes in the...
