摘　　要：以徐州张集煤矿7353综采工作面现场的实测数据为基础,利用ANSYS有限元分析软件,建立了综采工作面超前水力卸压消突的力学模型,模拟了综采工作面注水前后的应力变化和煤壁挤出位移量的变化,验证了水力超前卸压后上覆岩层的应力峰值向工作面煤壁深部移动以及工作面煤壁挤出的理论。In this paper, based on the spot test data in fully-mechanized working-face 7353 in Zhangji coal mining, the ANSYS soft is used. Then the mechanical model of pressure relief gas through preceding water force in fully-mechanized coal mining working-face has been founded. Through simulating the change of stress and the offset of mining rib before and after affusion, the theory of peak value stress over the coal layer will move into the deep place and the theory of working-face is extruded are proved.
