With Gequan Mine production capacity improving, the working face mining speed quickening, due to the limitation of complicated mine geological conditions, arrangement of regular large face shrinking, led to move down surface number increasing accordingly. The mine moved for 6 ~ 8 times per year on average, production capacity constrained. In view of the constraints, Gequan Mine actively explored innovation, after the 1523 working face of large tilt angle face and a series of complicated geological conditions moving down surface work, after the 1523 working face of large tilt angle face and a series of complicated geological conditions moving down surface work.
