    • Abstract
  • According to the laws of overlying strata movement above gob and gas migration, combined the scene of Lu'an Group Wuyang Mine 7801 fully mechanized caving face, by using FLAC3D to analyze the relative displacement between the roof and floor, the relative displacement between the left side and right side, the maximum stress, the laws of deformation and failure of high-level drainage roadway was determined under the mining influence, then the position of high-level drainage roadway was optimized.
