Numerical Simulation of Soft Main Roadway Repairing Technique in Shuanglong Coal Mine

Taking the support of Shaanxi Shuanglong Coal Industry as the project background, the paper simulated the deformation and failure in roadway under different support schemes with FLAC^3D program, analyzed the results of simulation experiments, obtained the variation characteristics of stress and the rules of the roadway surrounding rock movement in high stress regions.
