| Abstract: | The stress,strain and displacement in the release zone and concentration zone in front of the coal wall at 0908 fully mechanized working face in Pinggou Coal Mine are analyzed by using FLAC3D numerical simulation technology,the stress change conditions and deformation regularity in front of the coal wall as the first coming roof pressure are discovered,and the reason of increasing permeability at releasing stress zone of coal seam is found out to provide the scientific basis of gas drainage in releasing stress zone. |
