Abstract: In order to realize the safe and high-efficient mining of 1252(1) working face, which is long distance under-protecting coal stratum, we analyzed the gas emission situation of working face and the protected seam. Based on the characteristics of high outburst coal seam of the deep well coal seam group, we proposed the gas control mode of 1252(1) working face that " five tunnels in one face, gob-side entry retaining, "Y" style ventilation, surface borehole", which formed the pattern of the surface and underground stereo extraction. We also investigated the 1252(1) mining face gas extraction effect and gas accumulation conditions. The results show that the absolute gas emission rate of mining face is 120 to 130 m3/min; the gas extraction ratio reaches to 91%; extraction quantity of which concentration greater than 30% accounts for 85% of the total gas extraction; return current gas is from 0.3% to 0.4%. The simultaneous extraction of coal and gas has been realized.
