Under the condition of the top layered have irregular zone , due to the stress concentration caused by the upper leaf residual coal pillar , lower leaf will increase recovery difficult. This article reappear the scene of irregular top delamination area and the surrounding environment by FLAC3D numerical simulation software, receive the distribution condition of stress, displacement and the elastic energy of media under this condition, provide abundant basis for develop highly targeted production safety measuresa, solve the problem of data range is smaller,because the restriction of the detection equipment and other technical reasons detection equipment under the scene.
