Luo Kexiu focuses on fire, gas, carbon monoxide and other major hidden dangers in coal mine safety production. Rockxiu foam products are currently a new technology that can solve the problem of filling cavities in mine safety production, filling coal and rock fissures to prevent wind leakage, making airtight walls and firewalls to extinguish fires, and reinforcing broken roofs and strata.
, Rockshoe foam construction technology
Rockshoe foam is an injection product composed of resin and catalyst, which is used to seal air and gas, fill voids and holes, and reinforce coal and rock formations. This product only requires a special pump and a mixing gun powered by mine compressed air. The required compressed air pressure is .-. The high-pressure liquid pressure output by the pump is twice the supplied compressed air pressure. The volume of the pump is...The mass is approx. The two components, resin and catalyst, are mixed at a volume ratio of Roxiu foam hardens in minutes.
The application scope and function of Roxue foam
Fill the broken roof (coal) to prevent the accumulation of roof gas, prevent the broken roof coal from catching fire, and prevent the exchange of internal and external air.
Sealed walls block wind leakage: prevent internal and external gas exchange, prevent fire and benefit personal safety. When fracturing tunnels around closed walls, Rockshew foam can also be used to press into the cracks and plug leaks.
Filling the inlet and return air corners of the coal mining face prevents a large amount of fresh air from entering the goaf, prevents a large amount of gas from gushing out of the goaf, and prevents a large amount of air from entering the goaf for a long time, causing natural oxidation of leftover coal.
Filling of abandoned old tunnels and tunnels (coal bunkers): Preventing accidents caused by digging through the goaf during excavation and working face recovery. Preventing air leakage from abandoned tunnels (coal bunkers) and causing fires in the tunnels (goaf). .
Replace fly ash and sand to fill abandoned old tunnels and strengthen the roof of the tunnel mining face to prevent gas leakage.
Reinforce the broken coal and rock roofs and reinforce the roofs of tunnels in excavation and mining working faces in advance to prevent roof collapse. Reinforce coal pillars along gob excavation and block air leakage. Reinforce broken coal pillars to improve support and fill cracks in coal pillars to prevent air leakage and fire in coal pillars and goaf areas. Reduce the support density of return air tunnels in the working face.
Preventing roof collapse and fire in the working face or tunnel: increasing the stability of the roof. After injection of the high temperature point of the top coal body, it plays the role of fire extinguishing and reinforcement and sealing.
Advantages of Rockshoe foam technology
Rockshoe foam has: ① Rapid response ② High expansion rate ③ Better pressure resistance ④ Can directly extinguish fire ⑤ Simple construction technology ⑥ Wide range of uses. , Application of Rockxiu products in Heshan Coal Mine Rockxiu foam technology is used to block leakage in hot air ducts, extinguish fires, and seal air leakage in airtight walls. The width, height, and length of the hot air duct are about 1.5 meters, and the maximum concentration of carbon monoxide before filling is about 1.5 meters. After filling with Rockshew material, the maximum temperature at the entrance of the hot air duct has dropped to . Very good results have been achieved in blocking air leakage at hot air duct openings. According to the actual situation on site, a Roxue foam wall was constructed at the hot air duct entrance to effectively control the air leakage in the hot air duct. At the same time, the hot air duct is filled to effectively control the spontaneous combustion of coal seams in the hot air duct. , The implementation of Rockxiu fire prevention and extinguishing measures has effectively controlled the fire source in the hot air duct. From practical applications, it can be seen that pressure injection of Rockxiu is an effective means to prevent spontaneous combustion of coal seams in tunnels. It has the advantages of simple operation process, strong adaptability, flexibility, speed, timeliness, and high efficiency, so it has promotion value
Rapid spray sealing material for Rockshaw mine
It is a spray sealing material with good toughness used for Surface sealed. It consists of two components: resin and catalyst.
The two components are separately installed in a steel tank with pressure, mixed and stirred, and then sprayed using a special spray gun. After spraying, they are quickly formed without falling off or cracking.
