1.With water into the coal body, some gas is released and the content of the gas is lowered effectively
2. With the water injection put into effect, the dust can be lowered by over 80%,
the working conditions can be improved and the dust explosion accident can be avoided
3. Moistened coal bed prevents its spontaneous combustion
water injection into coal bed, drawing out methane.
1. With water into the coal body, some gas is released and the content of the gas is lowered effectively
2. With the water injection put into effect, the dust can be lowered by over 80%, the working conditions can be improved and the dust explosion an accident can be avoided;
3. Moistened coal bed prevents its spontaneous combustion;
4. With the pre-release drill hole and working face gas drawing system, the amount of gas emission and the amount of drill cuttings increase greatly, which has a better effect on burst accident prevention, releasing the crustal stress and the gas pressure effectively and avoiding the burst accident in course of the coal breaking.
5. The the problem of gas overrun while breaking coal body and drilling to prevent the burst accident has been solved, effectively preventing coal, gas burst and explosion.
The hole packer is made up of high pressure expanding rubber hose, middle steel tube, sliding sealing adapter and injection adapter.
Hole Sealing Diameter: 65 ~ 150mm ( Made according to user requirements )
Working Pressure:1~20MPa(Made according to user requirements)
Workflow: 5~8 tons of water can be injected per hour, and the gas emission depends on its concentration and pressure
Hole Sealing Depth:0.5m~3m
Coefficient of Hose Expansion: 60%~100%
Free-State Working Pressure MPa
Free-State Expansion Range(mm)
1. The gas drainage hole packer is quick, easy, and convenient to use.On the working site, with the injection adapter connected to the waterway or the air pump and the middle steel connected to the gas drainage the pipeline, the gas drainage hole packer is put into the drill hole, and the rubber hose of it expands under a certain pressure, carrying out the functions of the sealing hole, injecting water, and draining gas.
2.The gas drainage hole packer can be used repeatedly. After water rejection or gas drainage, with the pressure removed, it can be restored to the original state and can be taken out of the hole.
