Abstract: For the problems of tectonic soft coal development, unsatisfactory extraction effect in underground km long borehole and slow roadway drivage speed in the driving process of roadway in complex tectonic zone of Yangquan Mining Area outburst seam, the experimental study about gas extraction by ground vertical well fracturing in complex tectonic zone of outburst coal seam is carried out. According to the geological characteristics of No.3 coal seam in Xinjing Coal Mine, location selection and structure design methods for ground vertical well in complex tectonic zone are proposed, and the drilling and fracturing technologies of ground vertical well are obtained. Field test shows that the ground well runs 190 days continuously and the cumulative gas is 219 000 m³; the average daily volume is 1 261 m³ / d and the average gas concentration is 97%; it obtains the good effect of the gas extraction.
