Surrounding rock control technology for large-deformation stoping roadway after anchor removing, roadway enlarging and shed substituting

The invention discloses a surrounding rock control technology for a large-deformation stoping roadway after anchor removing, roadway enlarging and shed substituting. The surrounding rock control technology mainly comprises the steps that the roadway enlarging mode of the large-deformation stoping roadway is designed to be a roof-brushing roadway enlarging mode, and the section of the large-deformation stoping roadway is in a vertical wall arch shape; according to the design requirements of a repairing section of the large-deformation stoping roadway, anchor cables and anchor rods of the firstrow and the second row of surrounding rock of the stoping roadway are removed through an anchor removing machine; in the area where the anchor cables and anchor rods of the first row and the second row are removed, the surrounding rock of the roadway is subjected to manual coal side brushing and roof-brushing roadway enlarging through a pneumatic pick; after the roadway enlarging section is formed, a U-shaped steel shed i
