In order to study air leaking law in 23107 fully mechanized working face goaf of Xiegou Mine, tracing technology (SF6 as tracing gas), the air leaking speed was measured as 0.04～0.2 m/s, fluid calculation software ANSYS was simulated to detect the distribution depth of different air leaking speed to guide the fire prevention and control. The result showed that 0.04 m/s air speed with the contour line about 14 m away from the working face, 0.06 m/s air speed with the contour line about 12 m away from the working face, 0.2 m/s air speed with the contour line about 3 m away from the working face, 0.04～0.2 m/s air speed with the contour line about 0～3 m m away from the working face.
