Based on the analysis of mining face geology and equipment equipment,the roof control and equipment withdrawal scheme during the final mining period are constructed and applied in engineering.During the pullback of 11203 fully-mechanized caving face,the full section shield support method can improve the stability of the roof of the pullback channel,and the synergistic mode of the front withdrawal device,shovel truck and frame support truck can improve the mechanization degree and efficiency of the hydraulic support pullback,and realize the parallel operation of the hydraulic support pullback link.After field application,the recovery efficiency of hy-draulic support in 11203 fully-mechanized caving face has been significantly improved,and the goal of rapid recovery,reduced manpow-er and increased efficiency has been achieved.
