In order to realize mining in high gas mines in low gas states，a set of comprehensive gas treatment technology based on over-pre-pumping of coal seam gas，pumping while mining，and pumping and mining in the goaf area was proposed. The comprehensive gas treatment technology and measures for 81305 comprehensively drained working face in Baode Coal Mine were introduced，and the comprehensive gas treatment measures were recorded in detail，such as pre-pumping before mining of the present coal seam，switching between downdraft and updraft，pumping and drainage by buried pipeline in goaf area，pressure equalizing，air guide curtain and negative pressure spray setting，rationally distributed air flow，and closing at the end of mining. The results show that the volume of the gas pumping and drainage in the 81305 working face has reached a total of 18.549 1 million m³，and the comprehensive pumping and drainage rate has reached 81.07%，indicating excellent application effects. The comprehensive gas treatment technology combining various pumping and drainage methods can make the gas concentration in the comprehensively drained working face in Baode Mine safe and controllable during mining.
