Abstract Based on the unstability of roadway caused by high level tectonic stress, with numerical simulation, the response characteristic of roadway surrounding rock was analyzed, anchor cable grouting reinforcement was adopted in floor, with industrial experiment on the site. The result showed that the new support system could largely improve the initial support intensity and loading capability of the roadway surrounding rock, roof-to-floor convergence142 mm, two sides convergence 123 mm, the integrity and stability of roadway surrounding rock was achieved.
