Gas governance has always been a key focus in coal mining operations. The water-ring vacuum pump (gas extraction pump) is one of the effective methods for gas control. The extraction is carried out through methods such as pre-extraction, extraction while mining, extraction while mining, and extraction from the upper corner. Gas extraction pumps are classified as high-pressure pumps and low-pressure pumps. They are operated in a one-on-one backup mode and are equipped with three safety devices to effectively control the gas volume in the coal mining face and the return air system, ensuring it does not exceed the regulations stipulated in the "Coal Mine Safety Regulations" and guaranteeing the safety of the mine.
