| Abstract: | Through analyzing the rock properties of return slope of rock and the cause of roadway damage, combined with the numerical simulation, this paper proposed the support governance program of U-shaped steel bracket and short bolt anchoring, roadway corner plus anchor and shotcrete to close rock. The experiments show that the implementation of the program has achieved good supporting effect. |
