Filling and sealing of mining filling materials for coal mines, using filling materials as sealing walls, using Rockwell filling materials

Description :

　　Filling materials for mining use, filling materials for coal mines, sealing and sealing walls

　　Mining filling materialsLike a green leaf, it gradually turns yellow as the construction progresses, butFilling materials are used to fill sealed walls in coal minesThe effect is stable, and the product quality is clearly displayed, just like the veins of green leaves are still so clear and visible. If a company positions its products as small grasses, even in the best companies, they cannot grow into big trees.

　　1、 Mining filling materialsThe filling and sealing material for coal mine caving areas is developed to improve the construction speed of underground sealing and cavity filling in coal mines, and to enhance production efficiency. It is a material generated by a two-component reaction, which has good gas barrier and foaming properties. The material does not burn or support combustion, and should have outstanding explosion-proof and anti-static properties. It can block gas and have good fire prevention and extinguishing effects. After forming, the material has stable and long-lasting performance without cracking.

　　2、 Fill sealed walls with filling materials for coal minesAdaptation location and scope:

　　1. Fill coal and rock voids and cracks to prevent air leakage;

　　2. Sealing of toxic and harmful gases underground;

　　3. Constructing fire-resistant or rapid sealing walls;

　　4. Fill the high rise area of the roadway or working face;

　　5. Fire prevention and extinguishing in goaf or high rise areas.

　　3、 Mining filling materialsFeatures:

　　This product is a blocky foam prepared by compounding a variety of high molecular compounds with appropriate amount of crosslinking agent, stabilizer and curing agent, and reacting under specific conditions. The foam has light weight and good sealing performance. Produced by a two-component reaction, it has good gas barrier and foaming properties, and is widely used in temporary () sealing of coal mines and tunnels, filling of coal rock cavities and coal seam fractures, construction of firewalls, sealing of toxic and harmful gases, and roof caving support. It is particularly suitable for filling coal and rock cavities, various fractures, and air leakage channels in high emission areas, as well as blocking the upper and lower corners of the working face to prevent air leakage and gas outburst in goaf areas.

　　4Mining filling materialsThe filling and sealing material for coal mine caving area is formed by mixing the base material and catalyst in a volume ratio of 4:1 or 1:1, instantly foaming and rapidly expanding. The expansion ratio can reach 15~30 times of the initial volume. The expanded foam can solidify and harden within 2 minutes.

　　5、 Next, let's learn more about itMining filling materialsPerformance advantages of filling and sealing materials for coal mine caving areas:

　　1. The material is lightweight, easy to transport, and can greatly reduce the labor intensity of workers during closed construction;

　　2. When in use, it can be freely cut into different sizes and shapes of unit cells according to construction requirements;

　　3. Fast construction speed, can achieve a 5-minute closed tunnel;

　　4. The product is flame retardant and explosion-proof, sealed and non breathable, and the sealing performance is better when there is pressure on the top plate;

　　5. The product has a certain degree of plasticity and can maintain the compactness and airtightness of the tunnel after construction;

　　6. No need to purchase specialized equipment, and the product can be reused, saving costs;

　　7. Users can customize products of different strengths and sizes according to their usage location and requirements;

　　8. This product is environmentally friendly and is non-toxic, odorless, and pollution-free during use.

　　I am only targetingMining filling materialsGo ahead and say, I don't want to hype it up. We are a company and we need to focus on our work,Sealing effect of coal mine filling materials on sealed wallsIt's not something we can show just by talking. We have a responsibility to recommend it to you. If you happen to need it and happen to be interested, we welcome your inquiries.
