Abstract：Through long-term observations about deformation law of surrounding rock of roadway influenced by dynamic pressure in No.8 mine. The displacement speed as a dividing line, so around the working face was divided into six regions, including no effected area, the initial deformation area, speed deformation area, intense deformation area, slow deformation area, stable area. On the basis of great depth and complex geological conditions and dramatic impact on mining in No.8 mine, and then the supporting technology principle of first soft and after just and moderate soft were proposed, and development of the high priestesses and strong support technology.
