ROCKSHOW | ROCKSHOW Foam Application Scope and Function

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. ) Airtight 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 entrance 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.
) Fill abandoned old holes and slip holes (coal bunkers): Prevent accidents caused by digging through the goaf area during excavation and working face recovery. Prevent abandoned slip holes (coal bunkers) from air leakage causing slip holes (goaf areas). get angry.
) 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 in advance and reinforce the roofs of tunnels in excavation and mining working faces 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.
) The working face or tunnel prevents roof collapse and fire: it increases the stability of the roof and plays the role of fire extinguishing and reinforcing and sealing after the top coal is injected at the high temperature point of the coal body.
) Reinforcement of the coal and rock mass at the rear of the retraction bracket is used to advance the coal and rock reinforcement at the tail beam behind the roof of the bracket. The reinforced coal and rock mass not only increases the withdrawal speed of the working face, but also blocks the air leakage after the mining is exhausted to ensure fire safety.
) The working surface or tunnel prevents roof fall and fire. Increase the stability of the roof and play the role of fire extinguishing and circumferential sealing after injection at the high temperature point of the top coal body.
