Abstract: In the engineering background of the ultra-high roadway appeared in the process of mining roadway driving in a mine of Shanxi, it used the method of numerical analysis to calculate the displacement characteristics of two sides with the roadway height of 3～9m. The horizontal displacement and sinking of roadside midpoint became more obvious with the height of roadway increasing, when it was greater than a certain critical height, the displacement would significantly increase and there was a trend of overall slip. It revealed that the roadsides were the key parts of surrounding rock control in ultra-high roadway, anchor structure formed by using bolt to reinforce shallow surrounding rock had a binding effect on the surrounding rock, and it used the corresponding support technology of "three high" bolt.
