Features of large area deformation in Anda Mine +1 070 m level south roadway was taken as study object, the factors influencing roadway stability was analyzed, deep buried depth, floor without support and roadway lithology and mining were the main reason of the deformation. Anchor mesh gush + floor mooring + grouting combined plan was designed, the result showed that maximum convergence of two sides of roadway was 55 mm, relative approach of the floor and roof was 40 mm, surrounding rock deformation of roadway was controlled, meeting the needs of safe mining.
