    • Abstract
  • Taking bolt and mesh supporting roadway with large cross section in Lu'an Mining Area as research object. The paper studies the influence of roadway's section size on roadway surrounding rock's stability by theoretical analysis. Meantime, it also researches surrounding rock stress distribution laws of coal roadway with FLAC2D, and the change laws of surrounding rock stress under situation of different bolt-mesh supporting parameters. The research result is that the range of stress reduced and shear deformation is growing by nonlinear with roadway cross increasing. Besides, the long bolt improves the stress of depth rock and reduces the distribution of shear deformation. At last, the paper provides technical scheme that takes high strength, high pretension and large reinforced area as core.
