Several types of water ring vacuum pump drainage gas _

gas accident is the key of the need to pay attention to in coal mining industry in recent years, a mine can build on the dozens of innocent lives. Therefore, coal mining industry equipment safety is off and cannot be ignored, since the 1950 s in China for coalbed methane drainage, pumping capacity increasing, basic to achieve the objective of the coal mine safety, control the gas accidents. Using water ring vacuum pump/compressor drainage gas has the following basic form:

by coal mining and drainage points:

drainage before mining, namely the virgin coal seam of coal-bed methane drainage. Because of the mining area is wide, long line, generally speaking, there are dozens of kilometers. Bad work environment, so the requirement of water ring vacuum pump/compressor large swept volume, high vacuum degree, reliable operation. Now the water ring vacuum pump/compressor adopts international advanced technology, design and manufacture of gas can reach 500-70000 m3 / h, can completely meet the needs of the coal industry. The drainage method has gradually become the mainstream, this method not only become the guarantee of safety production, and coalbed methane will become a new clean energy, such a coal power of our country has strategic significance. Dig and smoke extraction, mining, the mining of coal seam is in the process of coalbed methane drainage. After drainage is taken, the discarded mine, mine roadway of coal bed methane drainage.

drainage way points:

drainage drilling method, the coal seam drilling, and adopts the technology of the loose, increase the release of coal bed methane area and guide, make the rapid release of coalbed methane. Reduce the release quantity in the process of mining. This method is effect is good, and the utilization rate of coalbed methane is high. Commonly used to drainage water ring vacuum water pump/compressor. Method of roadway drainage, the goaf roadway, mining roadway gas drainage, guarantee the safe concentration. Ground vertical Wells drainage; Hybrid method drainage, etc.

to the drainage layer target points:

mining drainage, adjacent layer drainage, goaf drainage, etc.
