摘　　要：万福煤矿主、副、风3个立井是目前世界上穿过冲积层最深的冻结井筒,冻结设计与施工难度大。3个井筒施工中,无一冻结管断裂,实现了井筒冻结段安全、快速、优质施工。对3个井筒冻结设计与施工技术做了梳理总结,为类似矿井冻结设计与施工提供了经验。The mine main shaft,auxiliary shaft and ventilation shaft in Wanfu Mine are the freezing shafts passed through the deepest alluvium in the present world.The freezing design and construction of the three shafts was very difficult.In the constructions of the three shafts,there was non freezing pipe broken occurred and the freezing sections of the mine shafts were safely,rapidly and high quality constructed.The freezing design and construction technology of the three mine shafts were prepared and summarized and could provide the experiences to the ground freezing design and construction of the similar mine shafts.
