摘　　要：顾南煤矿进风井井筒净直径8.6 m,冻结深度339 m,是地质条件较为复杂,断面大,施工难度大的矿井。冻结段采用液压滑模施工内层井壁,并重新设计了滑模模板结构,其井壁成型及封水效果好。文章总结了有益的施工经验。The net diameter of ventilation shaft in Gunan Coal Mine is 7m, frozen depth is 339 m which is a mine with complicated geological conditions, large cross-section and difficult to con- struct. The hytraulic slippery mold is used to construct inside lining of frozen shaft at frozen section, its structure is redesigned and the result of shaft wall forming and selling are well. The the- sis summarizes the beneficial construction experience.
