The new method for falling dust is to adding one kind of penetrative additive to the infusion water in order to improve the penetrative ability of water. The manufacturing process, characteristics, and application results of the rod-like penetrative additive (the penetrative rod) were discussed. The components and functions of the penetrative rode were studied carefully. Ultimately the components were decided after careful selection among molds, mainly including hygroscopic major components and auxiliary material. The result of on-site practical application show that such an addictive can increase the water penetrative ability effectively and has a remarkable effect on preventing dust production during coal seam excavation. The penetrating radius, the infusing velocity and the dust-preventive effect were systematically studied.
