To control dust pollution caused by open-pit coal mining and reduce or avoid the secondary hazards of existing dust suppressants to the environment. A biological dust suppressant was prepared through the synergistic effect of surfactant and enzyme-induced carbonate precipitation. The optimal ratio of biological dust suppressant was determined, and the dust suppressive effect and dust-fixing mechanism of biological dust suppressant were studied. The results showed that when the concentration of alkyl glucoside (APG) was 0.3%, the concentration of urea-CaCl2 was 0.6 mol/L, and the volume ratio of urease to urea-CaCl2 was 1:3, the wind erosion resistance of coal dust was enhanced by 86.69%. The adsorption of biological dust suppressant and coal dust is mainly due to the electrostatic interaction between surfactant and coal dust. The mineralization product is calcite type CaCO3, and its can consolidate coal dust due to the formation of intermolecular hydrogen bonds between CaCO3 and coal dust.
