Abstract: Aiming at the water leakage from anchor cable bore in Gucheng coal mine main inclined shaft which influences the support effect and construction schedule,We discover the roof has a lot of low strength mudstone rock strata that easy to produce cracks under the excavation.The cracks will lead to the water from the cracks in the infiltration which causes adverse effects tothe construction and support.Calculating the supporting schemes and grouting strengthening patameters of roof leakage parts in main inclined shaft by theory calculating methods and making the specific grouting cable anchor parameters by arranging testing section and constructing in 590~599m of main inclined shaft.Recording the mine pressure summarizing,thegrouting anchor cable reinforcement supporting water plugging measures have been successfully applied in the ancient city of mine water test section of inclined shaft.
