In order to solve the problem of soft rock roadways deformation instability of Zaoyuan Mine, according to the characters of soft rock roadways deformation instability and practical experiences of Zaoyuan Mine, the reserve with initial deformation reinforcement-after the release of surrounding rock pressure supporting method of secondary reinforcement was put forward. The initial state of the numerical simulation was adopted to determine the time to release initial supporting pressure, after comparing the supporting effect commonly used anchoring and shotcreting support +U arch was finally chosen; Field application showed that the support scheme could control the two sides of roadway roof subsidence and convergence effectively, the expected result of support was obtained, and the effective method to solve the problem of complex conditions of soft rock roadways support was provided.
