The silicate-modified polyurethane material used for coal and rock reinforcement in coal mines is a two-component grouting reinforcement polymer material. The product is constructed by mixing and injecting it into the coal and rock mass at a volume ratio of 1:1 using a dedicated pneumatic grouting pump and a mixing injection gun. The grout has good fluidity and can penetrate into small fractures in the coal and rock mass, effectively reinforcing loose coal. It has outstanding advantages such as low reaction temperature and good flame retardancy, making it suitable for rapid reinforcement of various fragmented coal and rock masses. It is mainly used for reinforcing fragmented coal and rock masses at mining and excavation work faces, repairing and reinforcing roadways and coal pillars, anchoring the full length of anchor rods and cables, and sealing gas drainage holes and water injection holes.
