Gas accident is the most important thing in the coal mine industry in recent years. Therefore, the equipment safety of the coal mine industry can not be ignored. Since the 1950s, China began to carry out CBM drainage, and the amount of gas drainage increased continuously, which basically achieved the goal of coal mine safety and controlled the occurrence of gas accidents. There are several basic forms of gas drainage by imported vacuum pump / compressor
According to the relationship between coal mining and drainage: pre pumping before mining, that is, the drainage of coalbed methane from the undeveloped coal seam. Because the mining area is wide and the pipeline is long, it usually has dozens of kilometers. The working environment is bad, so the imported vacuum pump / compressor is required to have large air volume, high vacuum degree and reliable operation. At present, the imported vacuum pump / compressor is designed and manufactured with international advanced technology, and the gas volume can reach 500 ~ 70000m3 / h, which can fully meet the needs of coal mining industry. This pumping method has gradually become the mainstream. This method not only becomes the guarantee of safe production, but also becomes a new clean energy, which has strategic significance for China, a big coal country. Pumping while excavating and mining while pumping, that is, CBM drainage in the process of coal seam mining. After mining drainage, namely abandoned mine, mining roadway CBM drainage.
The technology of gas drainage is to set up a gas pumping station on the ground and connect with the drainage borehole through the underground gas drainage pipeline system. When the pump is running, it will cause negative pressure, and the gas will be pumped out into the gas tank or directly supplied to the user. If the amount of gas extracted is small or unstable, it can be directly discharged into the atmosphere.
