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 *0 - *0 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 *0% 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.
