In view of actual situation of the local mining area of low gas coal mine, the gas source and the reason of gas overrun of working face are analyzed. The gas drainage using the overlying mined face goaf are raised. Through field application, the gas concentration in working face, corner, return airway are reduced, and the regulation effect is good. The mine safety get is guaranteed effectively.
