The damage of the surrounding rock seriously restricted the safe production of large mining height working face. Based on the wind and transportation roadway of 2302 working face, danger area of dominant layer development, high stress, geologic structure, field investigation were got by studying the range of loosing circle of surrounding rock, anchor-holding force of anchor bolt and site support effect.
