Abstract： Based on field conditions of coal roadway groups in the panjiayao coal mine and different positions of proposed road -way,six working models were established.Stress distribution on the corresponding conditions was obtained through analysis under excavate simulation on displacement , stress of anchor and anchor cable , plastic zone distribution, etc, which provide the theory reference and technical reference for similar conditions.
