4.Water use of bottom hole circulation grouting plug
The performance of the packer rubber tube; Oil resistant, wear-resisting, compression, acid and alkali resistance, corrosion resistance, oxidation resistance, anti-bending of anti-aging, fatigue performance is good, long life and other characteristics.
Inject water in the coal, exhaust gas.
Function 1. Inject water into the coal and release part of gas and decrease gas content in the coal efficiently. 2. After water injection come up to the effect, it can decrease above 80% dust and improve the workers work situation and put an end to the dust explosion accident. 3. Moist coal body, preventing coal body spontaneous combustion ignition. 4. After adopting advanced exhausting drill hole and working surface system, the amount of gas out-flow and drilling crumbs increase largely, it can effectively prevent gas outburst, release the geostress and gas pressure, so that it puts an end to the gas outburst accident while cutting the coal. 5. It solved the problem of cutting coal and preventing outflow gas while drilling gas over ranging. It can prevent coal gas out-flow and explosion efficiently.
Structure: The implement is made of high pressure rubber expansion hose, middle steel pipe, slide seal connector and injection pressure connector. Technical Parameter: Hole Diameter: 65-150mm(according to the customers' requirements). Working Pressure :1-6MPa(according to the customers' requirements). Working Flow: Inject water 5-8mt per hours, gas exhausted amount depending on concentration and pressure. Drilling Depth: 0.5-3M Hose Expansion Factor. Hose Expansion Factor: 60%100%.
Application Method and Note: 1. Use gas exhausted implement is rapid, simple and convenient. It needs to connect water or gas pump and the seal hole implement connector. Middle steel pipe and gas exhausted pipe connected. The seal hole implement plug into drill utterly, at a certain pressure the seal hole implement expansion realize seal hole, water injection or exhausted gas. 2. Gas exhausted implement can be used many times, when water injection or exhausted gas is over, get rid of the pressure it can revert, take out seal hole implement. 3. No pressure in using seal hole implement.
