摘　　要：为了实现大采高综放面高产高效优化研究,针对新巨龙矿2301大采高综放面,在散体介质的相关理论指导下运用FLAC3D软件建立模型进行数值模拟,理论分析合理的放煤步距和放煤方式,为厚煤层大采高综放面有效提高采出率实现高产高效提供理论依据。To achieve high yield and efficiency in large-- mining-- height fully mechanized caving face, the authors present the numerical simulation by model building with FLAC3D software under the guidance of the related granular media theory, which theoretically analyzes the reasonable coal drawing interval and mode and provides a theoretical basis for increasing the recovery ratio in large--mining--height fully mechanized caving face with thick coal seam.
