　　Coal seam water injection refers to injecting pressure water into the coal seam through boreholes before mining. Pre wetting the coal can reduce the amount of coal dust generated. Injecting water evenly into the coal body, with a moisture content of at least 4%, can prevent protrusion from occurring. Water changes the mechanical properties of coal, making stress distribution more uniform, reducing the release rate of elastic energy, lowering power, and decreasing the emission rate of biogas, which can be reduced by 90% compared to the initial release.

　　1、 Composition of FKSS-63/4 Gas Injection Sealing Device:

　　The sealing device consists of a high-pressure rubber expansion hose, a pressure relief valve, and a quick connector.

　　3、 Instructions for using KSS-63/4 gas injection sealing device:

　　1. Using FKSS-63/4 gas injection sealing device is fast and easy. Simply connect the waterway at the work site to the sealing device, insert the sealing device completely into the borehole, and under a certain pressure, expand the sealing device hose to seal the hole and inject water to break the coal.

　　2. The FKSS-63/4 gas injection sealing device can be reused multiple times. After the injection is completed, the pressure is released and the sealing device can be restored to its original state. Remove the sealing device.

　　3、 The main functions of FKSS-63/4 gas injection sealing device are:

　　1. Moisture enters the coal body, releasing some gas and effectively reducing the gas content in the coal body;

　　2. After water injection achieves the desired effect, it can reduce dust by over 80%, improve the working environment for workers, and prevent dust explosion accidents;

　　3. Moisturizing coal to prevent spontaneous combustion and fire;

　　4. High pressure water injection, coal crushing, reducing pyrotechnic products, lowering costs, and enhancing workers' sense of safety;

　　5. Using a sealing device to break coal can effectively prevent coal and gas outbursts and explosions.

　　4、 Technical parameters of FKSS-63/4 gas injection sealing device:

　　Sealing diameter: 30-120mm (can be processed according to user requirements)
