The invention provides a compound type environment-friendly dust suppressant as well as a preparation method and application thereof. The compound type environment-friendly dust suppressant is characterized in that based on the total mass of the dust suppressant, the dust suppressant is prepared from the following components in percentage by mass: 18 to 60 percent of an adhesion composition, 5 to20 percent of a coagulation composition and 15 to 45 percent of a moisture absorbent, wherein the adhesion composition is a composition of polyvinyl alcohol, carboxymethyl cellulose and Na2SiO3; the coagulation composition is a composition of polyacrylamide and sodium tripolyphosphate. The compound type environment-friendly dust suppressant provided by the invention is easy to store and low in cost, and also has a relatively good dust suppression effect; the compound type environment-friendly dust suppressant is especially suitable for dust suppression of a pit road surface of an open coal mine. 本发明提供种复合型环保抑尘剂及其制备方法和应
