Aiming at the frequent gas overrun in upper corner during fully mechanized mining face mining, the surface mining well was used for gas extraction in the fracture zone of the mining area. Based on the theory of “O” shaped circle formed after the mining and the experience of other mining wells in Qinshui Basin, the optimal layout of mining wells is determined. The test results show that the horizontal level is 42 m away from the side of the air return roadway, and the vertical level is 22 m from the end of the drilling to the bottom of the goaf. After the operation of the mining well, the gas concentration in the upper corner decreased and stabilized to 0. 35% from 0. 76%, and the gas emission from the working face was 2. 08 m³ / min lower. In addition, the continuous extraction during and after mining was realized. The high efficiency extraction of the mining well effectively ca eliminate the gas overrun in the fully mechanized mining face, and the promotion and application in Yuecheng Mine can provide a solution for gas control in other similar mines.
