Abstract：No.1 Mine Auxiliary Shaft of Cixi Mine was 1 341.6m in depth and 8m in a net diame‐ter.The depth of the mine shaft ingate was over 1 000m.The north side ingate was 17.0m in a length , high in geostress ,soft of the surrounding rock and poor in the stability.A combined support plan was applied with a bolt/steel mesh/band/anchor/shotcrete/grouting as the primary support and a U steel square support ,reinforced concrete lining+enhanced floor reinforcement as the secondary support.An excellent support effect was obtained and a long time stability of the mine roadway could be ensured.In the support construction of the north side ingate ,the mine strata pressure monitoring and measuring was con‐ducted ,the results was compared to the numerical simulation results.A study on the support technology was conducted and the feasibility and effectiveness of the support plan was verified.
