Injection sealing device 

 Injection sealing purpose for the coal seam injection 
 Drilling diameter 50 (mm) drilling depth (m) 
 Drilling angle (°) Dimensions 22/38 (mm) 
 Weight 1 (t) Spindle speed 10 
 Drill pipe diameter 40 
 A. Use: injection of coal dust, drop coal pressure to crack coal, emissions of gas. Two. Features: 1. Water into the coal, the release of some gas, and reduce the gas content of the coal body. Two. After the injection to achieve the desired effect, can reduce more than 80 percent of dust, to improve workers' job environment to prevent dust explosion. 3. Wet coal, prevention of spontaneous combustion of coal. 4. High pressure water injection, crushing coal, to reduce fire and industrial products, reduce costs, increase workers' sense of security. 5 Use of sealing broken coal, can effectively prevent the coal and gas outburst and explosion. Three. Structure: sealing, high pressure plastic expansion pipe, safety valve, quick attachment is composed. Four. Technical parameters: Sealing diameter: 30-120mm (according to user needs) working pressure: 1-8Mpa (according to user needs) safety valve starting pressure: 0.4-0.5Mpa work flow: per hour injection 4 t -4.5 t sealing depth: 1M-8M hose expansion coefficient: 60% -100% of the use of methods and precautions: 1 infusion for coal seam sealing device fast, simple, just the job-site waterways and sealing device connectivity. the sealing device is fully inserted into the boreholes, under certain pressure, sealing hose expansion to achieve sealing, water breaking coal. Infusion for coal seam sealing device can be repeatedly used several times after the injection relieved the pressure, sealing can be recovered, remove the sealing device. Sent to insert the sealing device and recycling sealing non-pressure operation. 4, the sealing device work front are not allowed operations.
