Roxue foam is a mining injection product composed of resin and catalyst used to seal air and gas, fill voids and holes, and reinforce coal and rock formations. The construction of Luo Kexiu only requires a dual-liquid grouting pump and an injection gun. Using mine compressed air as power requires the compressed air pressure to be between -. The high-pressure liquid pressure output by the pump is the supply compressed air pressure. Land times. The two components, resin and catalyst, are mixed in a volume ratio of Roxiu foam hardens in minutes.
- Application scope and function of Roxue foam
- Sealed wall to block wind leakage: prevent internal and external gas exchange, prevent fire and benefit personal safety. During fracturing of the tunnel around the closed wall, Rockshew foam is also pressed into the cracks to plug leaks.
- Fill the broken roof (coal) to prevent the accumulation of roof gas, prevent the broken roof coal from igniting, and prevent the exchange of internal and external air.
- Filling the entrance and return air corners of the coal mining face prevents a large amount of fresh air from entering the goaf area, prevents a large amount of gas from gushing out from the goaf area, and prevents a large amount of air from entering the goaf area for a long time, causing natural oxidation of leftover coal.
- d. Fill abandoned old tunnels with fly ash and sand to strengthen the roof of the tunnel mining working face to prevent gas leakage.
- Filling of abandoned old tunnels and slip holes (coal bunkers): Preventing accidents caused by digging through the goaf area during excavation and mining on the working face. Preventing accidents caused by air leakage in abandoned slip holes (coal bunkers). gob) fire.
- Reinforce the broken coal and rock roofs in advance to reinforce the roofs of tunnels in excavation and mining working faces to prevent roof collapse. Reinforcement of coal pillars along the gob excavation, plugging of leakage wind, reinforcement of broken coal pillars, improvement of supporting force and filling of cracks in coal pillars.
- Prevent air leakage and fire in coal pillars and goaf areas and reduce the support density of return air tunnels on the working face.
- Advantages of Rockshaw foam:
- ① Rapid response
- ② High expansion rate
- ③Good pressure resistance
- ④Can directly extinguish fire
- ⑤Simple construction technology
- ⑥Wide range of uses.
