Beschreibung
Zusammenfassung:	The invention provides a method and a system for gas pumping of high-gas coal mines. The method for gas pumping of high-gas coal mines includes: setting a wellhead of a horizontal well on the ground; setting the horizontal well communicated with the wellhead of the horizontal well in a fissure zone; and setting a vacuum pump on the ground and enabling the vacuum pump to extend into the wellhead of the horizontal well to pump the horizontal well. The system for gas pumping of high-gas coal mines comprises the horizontal well and the pump, wherein the horizontal well is arranged in the fissure zone and communicated with the ground, and the pump is positioned on the ground and communicated with the horizontal pump. Horizontal well drilling and coal mining theories are organically combined to transplant underground works to the ground for implementation, so that risks of coal mine underground construction are reduced.
