Mining method of 7607 working face was towards the long wall retreating, which was a comprehensive mechanization method of full-seam mining along bottom to low-roof coal, and roof was managed by all across the fall method. Middle-low part 3# coal seam in Shanxi group was exploited, its coal seam occurrence was stable and average depth was 6.06 m. Failure and deformation reasons of surrounding rock were analyzed, surrounding rock control technology and concrete geological condition of No.3 coal seam working face were studied, which not only determined supporting form and parameters, but also had field monitoring and optimization on support effect.
