Abstract：This paper aims to present the dust suppression effects of nano-scale solution, for this a laboratory experiment was conducted with silica, copper oxide and graphene oxide, which were selected as the research objects, and their characters of anti-evaporation, hygroscopicity and wind erosion resistance as the test indexes. The experimental data suggested that in terms of integrated dust suppression performance graphene oxide was better than silica followed by copper oxide, of which graphene oxide content of 1.5％ was the best, and its wind erosion resistance was 254.43 times as high as water owing to its low surface tension and high viscosity. In addition, observation of micro-structure of the surface of dust sample showed that particulates in nano-scale solution were filling the gaps amongst particles of test dust, resulting in functions of dust particles fixation and coupling, contrary to silica and copper oxide whose particulates were dispersed, grapheme oxide particulates were in colloidal and continuous shapes, so that it possessed a stronger function to suppress and stabilize dust.
