  • Published Date: March 19, 2013
    Graphical Abstract
    • Abstract
  • The distribution laws of advanced support pressure and the deformation characteristics of coal-pillar at fully-mechanized mining face are analyzed by FLAC3D numerical simulation. On the basis, the stress distribution characteristics of surrounding rock mining roadway of mining area are analyzed. The results show that the rational stop mining position of working face is away from the main roadway of 76 m.
