Permanently fitted to the ejection to eject SURFACE AIR downhole methane

摘要

"Fixed installation for ejection to eject air to the surface downhole with methane", operates without the use of electricity. It can be assembled easily accessible, low-cost, quick installation of plastic pipes and strengthened under the roof.; The basis of the ejection - natural extractor methane due to the level difference downhole and atmospheric air on the surface where a funnel-diffuser air inlet turbulent atmospheric flow is converted into directed, at times increases the volume rises to the surface downhole air with methane, which excludes its samovzryv in a coal mine ..
