Algorithm Optimization Applied in the Selection of Stress Distribution Supported by FLAC3D Numerical Simulation

Aiming at the problem of rockburst happened during deep mining activity in Inner Mongolia area, FLAC3D numerical simulation software was used to analyze the supporting effect of different supporting methods. Through the analysis of the influence of the three methods of slot-tube anchor bar, resin bolt and bolt-mesh combined support on the stress, displacement and elastic strain energy distribution of roadway surrounding rock, it is found that the bolt-mesh combined support can effectively reduce the elastic strain energy and the potential of rock burst.
