The article uses the FLAC3D numerical software to analyze the roof subsidence displacemen under different supporting strength. After comparing, combined with large dip angle fully mechanized caving face support stability analysis, determine the reasonable support working resistance at the fully-mechanized caving face in the big angle specially thick coal seam, to provide a basis for supports selection at the fully mechanized caving face.
