摘　　要：以A特厚煤层煤矿39204工作面为例,介绍一种适用于特厚煤层动压巷道的小煤柱护巷技术。采用FLAC3D数值模拟软件对特厚煤层动压巷道围岩应力分布及变形情况进行仿真分析,结合小煤柱动压巷道控制理论,设计了特厚煤层小煤柱动压巷道控制方案,并将该方案应用于A特厚煤层煤矿工程实践,确认所提出的特厚煤层动压巷道小煤柱护巷技术具有较强的可行性。Taking 39204 working face of extremely thick coal seam of A Coal Mine as an example,a small coal pillar roadway protection technology suitable for dynamic pressure roadway of extremely thick coal seam was introduced.FLAC3D numerical simulation software was used to simulate the stress distribution and deformation of the surrounding rock of the dynamic pressure roadway of extremely thick coal seam.Combined with the control theory of dynamic pressure roadway with small coal pillars,the control scheme of dynamic pressure roadway of extremely thick coal seam with small coal pillars was designed,and the scheme was applied to the engineering practice of extremely thick coal seam of A Coal Mine.It is confirmed that the proposed small coal pillar roadway protection technology of the dynamic pressure roadway of extremely thick coal seam is of strong feasibility.
