Abstract：In view of the occurrence conditions of coal seam group of Wanbei Mining Area,on the analysis of the existing gas extraction technology application condition at home and abroad,on the basis of the research,we formed a typical underground stereoscopic extraction in the mining area and up and down stereoscopic extraction technology for well,integrated technological process of hydraulic slotting pressure of coal seam with low permeability of high ground stress,obtained the technical mode of coal mine gas treatment.The practice shows that the targeted gas stereoscopic extraction mode and process technology can ensure the gas efficient control and the safe production of coal mine.
