Overview of 51,101 W working face and schematic diagram of fault location and water inrush. (a) The coal seam dip angle is approximately 9°. (b) The 51,101 W working face and FX fault relationship plan, the strike of the FX fault is 40° with respect to the mining direction of the working face. (c) The actual fault waterproof coal pillar of 51,101 W working face are 30 m and 50 m wide (d) The angle between fault F8−2 and the coal seam is 79 °, and the angle between fault FX and the coal seam is 89 °.
