Abstract:
      The stability of roadway itself is usually combined by comprehensive factors, but under dynamic pressure, it is mainly caused by surrounding rock stress redistribution near the working face, and the stress asymmetry at both sides of roadway. In this paper, the support scheme of 150101 dynamic pressure roadway is analyzed and studied. Through the FLAC3D simulation, an optimized support scheme can make the roadway continue to use under the influence of dynamic pressure.
