  • Published Date: July 19, 2017
  • In order to overcome the severe deformation of retained roadway of bilateral goafs by spiral drilling of thin seam, FLAC3D numerical simulation was adopted to analyze the deformation characteristics and stress change of surrounding rock with different width of filling body, the retained roadway stability reinforcement method with filling body was proposed, the parameters of the surrounding rock stress, the displacement of roof and laneway’s side, and the failure height of overlying strata are calculated under different width of filling body, the relationship between filling body width and deformation of surrounding rock of retained roadway was analyzed, and the reasonable width of filling body was determined. The results show that the filling body with 1.0 m width could meet the stability requirement of retained roadway of bilateral goafs in thin seam.
