Product Description
Product
Gas drainage hole sealing device FKSW II-38
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.
Structure:
The hole sealing device is composed of high pressure rubber expansion hose, middle tube, sliding seal joint and injection pressure connector.
