Structure:
It is made of high pressure expansion hose, safety valve and rapid-acting coupling.
Application:
Coal injection, dust-fall, coal pressure reduction, coal-crack, methane drainage, ect.
Function
Water into the coal, gas release part, effectively reduce the coal gas content
It can reduce the 80% dust, improve workers' working environment. And completely eradicate dust explosion accident when water injection reaches the desired impact;
High pressure water injection, breaking coal mass, reducing cost, and increase the security of workers.
Use the hole sealing device to efficiently prevent the gas stress and explosion.
