Abstract in view of the rapid deformation of the auxiliary transportation roadway in the second area of Zhaojin Mine, the stress distribution of surrounding rock, the basic law of pressure behavior and the displacement vector of surrounding rock were analyzed and demonstrated. The support design of combining high strength anchor cable with rigid passive support was established based on the principle of coupling support, which effectively solved the problem of roadway maintenance in high stress and dynamic pressure concentration area.
