The silicate-modified polyurethane material used for spraying to plug air leaks in coal mines has excellent adhesion, flame retardancy, water resistance, corrosion resistance, and a certain toughness. It can still plug air leaks and seal when deformed along with the rock layer and wall, and also has a certain reinforcement effect.

Phenolic resin foam material for coal mine filling and sealing has excellent flame retardant properties, high expansion ratio and low reaction temperature, and is particularly suitable for large volume filling.
The polyurethane material used for coal mine water plugging has extremely high strength, excellent bonding force and solvent corrosion resistance. In a water environment, the mixed resin can expand at a high rate and densely fill all gaps. It also has a certain toughness and can deform with the rock layer while maintaining the plugging effect.
The silicate-modified polyurethane material used to reinforce coal rock in coal mines has excellent compressive strength, adhesion, flame retardancy, and solvent corrosion resistance, and has a certain toughness. It can be smoothly cured and maintain good strength even in a water environment. It can deform with the rock formation while maintaining the effect of sealing and reinforcement.
