In the process of coal mining and transportation, it is inevitable to produce a large number of coal powder, which has many adverse effects, causing pneumoconiosis and even explosion, bringing huge hidden dangers to the safety of people's lives and property. In order to reduce the occurrence of this kind of engineering disaster, surfactant is often used for wetting and dust reduction. In this study, the coal powder of the left 2 working face at No.65 layer in Xinxing Coal Mine is taken as the object, and four kinds of surfactants are used to study the osmotic effect. The comparative analysis is carried out from the penetration forms, the change of contact angle, and the unit cost. The method of selecting reagents under different engineering conditions and requirements is obtained, which provides an effective way for reduction of coal powder in coal mine, and has a certain reference value.
