摘　　要：综合采用理论计算与FLAC3D数值模拟方法,分析了大倾角特厚煤层综放工作面不同支护强度下顶板下沉位移量。经分析对比,并结合大倾角综放工作面支架稳定性分析,确定大倾角特厚煤层综放工作面支架合理支护强度与工作阻力,为现场支架选型提供依据。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.
