Numerical Simulation on Strengthening Supporting Mechanism and Effect of Anchor-Cables in Deep Coal Mine Roadway
Prestressed anchor-cables supporting technology has become the primary measure for reinforcing the roadway of deep coal mine and complex geological conditions. In this paper, fast Lagrangian analysis of continua (FLAC3D) code is used to analyze the laws of stress, deformation and failure of surrounding rock with and without roadway supporting by anchor-cables. The supporting action mechanism and effect of anchor-cables have been investigated into systematically. The results show that the anchor-cables supporting is adopted at reasonable positions of the roadway in good time which can improve the stress states of deep surrounding rock, decrease the range of failure zone around the roadway, control the roadway deformation effectively and maintain the stability of roadway.
