　　1、 Advantages of organic filling material technology for mining:

　　1. Fast ignition, high foaming ratio, high filling efficiency, completely non flammable, safe to use, eliminates problems such as heartburn and smoke, and has reliable safety for use.

　　2. Solvent free, low odor, high flash point, good flame retardancy, no harmful gases produced during construction, especially suitable for construction in enclosed tunnels.

　　2、 Application scope of organic filling materials for mining:

　　1. Fill the broken roof (coal) to prevent the accumulation of roof gas, prevent the combustion of broken roof coal, and prevent the exchange of internal and external air.

　　2. Sealed wall blocking air leakage: prevents internal and external gas exchange, prevents fire, and is conducive to personal safety. When the roadways around the closed wall are fractured, Rockhew foam can also be used to press into the cracks for plugging.

　　3. Filling of inlet and return air corners in coal mining face; Prevent a large amount of fresh air from entering the goaf and prevent a large amount of gas from escaping from the goaf; Prevent long-term large amounts of air from entering the goaf, causing natural oxidation of residual coal.

　　4. Filling abandoned old tunnels and coal bunkers: to prevent accidents caused by excavating through the goaf during excavation and backfilling of the working face; Prevent air leakage from abandoned coal bunkers, which may cause combustion in goaf areas.

　　5. Replace fly ash and sand to fill abandoned old alleys; Strengthen the roof of the roadway mining face to prevent gas leakage.

　　6. Strengthening broken coal and rock roofs; Advance reinforcement of the excavation and mining face roadway roof to prevent roof collapse. Strengthening coal pillars and blocking air leaks along the goaf; Strengthen the broken coal pillars and improve their support capacity; Fill the cracks in the coal pillar to prevent air leakage and ignition in the coal pillar and goaf; Reduce the support density of the return airway in the working face.

　　7. Preventing roof collapse and ignition in the working face or roadway: increasing the stability of the roof, injecting high-temperature points of the roof coal body to extinguish fires and reinforce sealing.

　　3、 Method of using organic filling materials for mining:

　　1. There is no need for slurry preparation on site. Simply connect components A and B to the grouting pump system, adjust the volume to 1:1, and mix them automatically through a static mixer to achieve grouting.

　　Before grouting, it is advisable to leave the two components at the corresponding ambient temperature for more than 12 hours. On site material temperature, environmental moisture, mixing conditions, etc. may have a certain impact on the solidification time, rate, and strength of the slurry.

　　Mining organic filling material is a type of organic polymer dual liquid (A/B component) foaming/filling grouting material, which has the characteristics of low reaction temperature, high foaming ratio, and non flammability. It is suitable for quickly filling the voids of broken coal and rock layers and sealing air leaks. When used on site, simply mix component A and component B in a volume ratio of 1:1 through a dual liquid injection pump and inject grout automatically. Its rapid response, high expansion rate, and good overall pressure bearing capacity provide an economical, fast, and safe solution for hollow filling. With its outstanding anti-static performance and high fire rating, Rockhew foam E is also applicable to the prevention and control of mine fires and the sealing of underground heat sources.
