In order to solve the problem of the effect of mining thickness on the abutment pressure distribution,the working face of 1301N in new Julong Mine was taken as background, the distribution of abutment pressure under different exploiting thickness through FLAC3D was adopted. By contrasting the abutment pressure distribution for tendency of the working face with 3、6 and 9 m thickness of the coal, the result showed that stress concentration area of tendency decreased with the increase of the thickness of coals and the peak point on tendency transferred to the deep coal pillar, the distance of limit equilibrium zone and the increasing stress area and the average stress value increased.
