Product Details:
High abrassion resistant Water type gas drainage hole sealing
device is suitable for different working principles and
performances and meeting different working environments according
to specific requirements of different coal mines, and have obtained
Mining Products Safety Label.
Application: water injection for coal, gas drainage
Function:
1 By injecting water into coal mass, some of the gas can be
discharged, thus the gas content of the coal mass can be
effectively reduced.
2 If water injection achieves the desired effet, the dust can be
redued by more than 80%, thus improving the working environment and
avoiding dust explosion accident.
3 It can dampen the coal and prevent spontaneous combustion of
coal.
4 After adopting advance drainage bore hole and working face
drainage system, the gas gushing amount and drilling cuttings
amount at the drainage borehole increases obviously, thus reducing
the risk of outburst greatly. It helps to release the ground stress
and gas pressure effectively and avoids accidents in coal cutting.
5 It has solved the problem of transfinite gas in coal cutting and
outburst prevention drilling, and can efectively prevent coal and
gas ouburst and explosion.
