    • Abstract
  • In order to solve the safety support in special cross mining tunnel, taking 2114 working face in mining area total wind drift mining as the background, we use rock mechanics test to analyze and obtain that the lithology of clay rocks and mud cementation sandstone is strong rheological swelling; according to the knowledge of mechanical theory, we derive that mine mining depth is 23.6 m; failure laws and characteristics of roadway surrounding rock are analyzed and proposed for such cross mining roadway surrounding rock control technology. According to the industrial test, the method can ensure the safety of the tunnel, and achieve good results.
