    • Abstract
  • Taking IV621 airway as the research object, we researched deformation laws of surrounding rock and stability control of deep soft rock roadway and applied to the field by combining methods of site investigation, numerical simulation, and engineering practice. The results show the time effect of the surrounding rock displacement of roadway surface and deep roadway during excavating tunnel, analyze deformation of the surrounding rock controlled by the anchor support, anchor cable support and joint support. The deformation of roof and floor of roadway within 95 mm and deformation amount of two walls within 100 mm in filed practice can meet the requirements of coal mine safety production.
