The Special Service of  Water injection and Hole-sealing Device for Coal:

Coal injection /dust-fall/coal pressure reduction/coal-crack/methane frainage

 The Function of Water injection and Hole-sealing Device for Coal:

1.Moisture enters into coal mass, releasing some gas, and reducing the gas content in the coal body.

2.It can reduce the 80%dust, improve workers'working environment, and completely eradicate dust explosion accidents when water injection reaches the desired impact;

3.Wetting coal mass to prevent the spontaneous ignition of coal body.

4.High pressure water injection, breaking coal mass, reducing cost, and enhancing the worker's feeling of safety;

5.Use the hole sealing device to efficiently prevent the gas stress and explosion.
