The manufacturing process, characteristics, and application results of a rod-like penetrative additive (the penetrative rod) were discussed. The components and functions of the penetrative rod were studied carefully. A large number of orthogonal combined tests were carried out and over 100 sample molds were made. Ultimately the components were decided after careful selection among these molds, mainly including hygroscopic major components and auxiliary material. The results 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.
