Abstract: In the process of coal mining, some roadways may experience deformation, mesh tearing, and roof leakage due to soft
surrounding rock, unreasonable support design, or excessive mine pressure. In order to ensure the safe use of the roadways, it is
necessary to repair them. After multiple renovations, the loose zone of the surrounding rock in the roadway is becoming larger and
the support is becoming more difficult. Based on the actual situation of 31 transportation rise in Dahebian Coal Mine, a combined
support form of "anchor net+U-shaped shed+grouting anchor cable+guniting+grouting" was adopted. In order to ensure the safe
construction of the repair, a series of safety measures had been formulated.
