Water Injection Hole Packer - China

Water injection hole packer is used to inject water to coal, which can

reduce the gas content and dust.

As a result, it can improve the safety

coefficient of mine construction and production greatly.

It is composed

of high pressure inflation rubber hose, safety value and rapid- acting

coupling.

And it can be used repeatedly for 30 - 50 times.

The function of water injection hole packer:

It can inject water into the coal bed which can release some gas.

So it can reduce the gas content effectively.

The dust can be reduced by 80% if the water- flooding effect is good.

So it can improve the workers' operation conditions greatly and prevent the dust explosion accident effectively.

The water can humidify the coal bed, which can prevent the auto- ignition of the coal.

The water is injected in high pressure, which can crush the coal.

So it can lessen initiating explosive devices, lower the cost and increase the workers' sense of safety.

Breaking coal with water injection hole packer can prevent the explosion of coal and gas effectively.
