Rockxiu, mining filling material, mining Rockxiu, Malisan, Rockxiu manufacturer, Rockxiu foam construction technology technology Rockxiu foam is an injection product composed of resin and catalyst, used for sealing Air and gas, filling voids and cavities, and strengthening coal and rock formations. This product only requires a special pump and a mixing gun, uses mine compressed air as power, and requires the compressed air pressure to be at. The high-pressure liquid pressure output by the pump is twice the supply compressed air pressure. The volume of the pump is approx. The first component resin and the catalyst are mixed in a volume ratio. The two components are automatically activated by compressed air and react quickly to generate foam. After foaming, the volume quickly expands to twice the original volume and is directly injected into the area to be treated. After expansion, Rocxiu foam hardens within minutes. The application scope and function of Roxue foam
) is to 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 air leakage, prevent internal and external gas exchange, prevent fire and are beneficial to personal safety. When the tunnel around the closed wall is fracturing, Rockshew foam is also pressed into the cracks to plug the leaks.
) 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 of 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.
) Fill abandoned old tunnels and slip holes (coal bunkers) to prevent tunneling and mining of the working face from digging through the goaf area, causing accidents. Prevent abandoned slip holes (coal bunkers) from leaking air and causing slip holes (goafs). area) gets angry.
) Replace fly ash and sand to fill abandoned old tunnels to strengthen the tunnel roof of the tunnel mining working face to prevent gas leakage.
) Reinforce the broken coal and rock roofs in advance and reinforce the tunnel roofs in the excavation and mining working faces to prevent roof collapse.
) Reinforcement of coal pillars along gob excavation, blocking of air leakage, strengthening of broken coal pillars, increasing support force to fill cracks in coal pillars, preventing air leakage and fire in coal pillars and goaf areas, and reducing the support density of return air tunnels on the working face.
) The roof plate remains intact after the roof collapse of the working surface and the side of the sheet are reinforced to prevent personal accidents during manual roofing. The bracket has sufficient support to facilitate the rapid movement of conveyors and racks. ) Reinforces the coal and rock mass at the rear of the retraction support, which is used to reinforce the coal and rock at the rear tail beam of the support roof. The reinforced coal and rock mass not only increases the retraction speed of the working face, but also blocks the air leakage after the mining is exhausted, ensuring fire prevention. safety.
) The working face or tunnel prevents roof collapse and fire and increases the stability of the roof. After injection at the high temperature point of the top coal body, it plays the role of fire extinguishing and reinforcement and sealing.
Advantages of Rockshaw foam technology Rockshaw foam has rapid response, high expansion rate, good pressure resistance, and can directly extinguish fires. The construction technology is simple and widely used.
