Numerical Simulation and Parameter Optimization of Advance Anchor Bolt Support in Fault

In view of the conditions that driving roadway crossing the fault and taking into account broken surrounding rock in the fault zone, small rock strength, and greater pressure on the roadway of the 103 mining area of Yuandian Mine. These conditions bring greater difficulty such as causing digging after repairing and supporting strength could not meet the production needs of the safety production. So we propose advance anchor bolt support and using FLAC^3D simulation software to analyze the supporting effect of advance anchor bolt through comparative analysis of stress and displacement distribution of roadway under different parameters. Finally, we get the most effective and economical advance support program.
