1、 Usage: Coal body water injection, gas drainage.
2、 Function
1. Water enters the coal body and releases some gas, effectively reducing the gas content in the coal body,
2. After water injection reaches the desired effect, it can reduce dust by more than 80%, improve the working environment for workers, and prevent dust explosion accidents,
3. Wet coal body to prevent natural combustion of coal body
4. After adopting the advanced discharge drilling and processing face drainage system, the amount of gas emission and drilling debris in the discharged drilling holes significantly increased, playing a good anti outburst effect, effectively releasing ground stress and gas pressure, and preventing the occurrence of sudden accidents during coal cutting
5. Solved the problem of gas exceeding limit during coal cutting and anti outburst drilling, effectively preventing coal and gas outburst and explosion.
