摘　　要：立井基岩冻结井壁的计算理论至今尚处于探索阶段,本文综合已设计建成西部矿区的几个基岩冻结立井的实例,同时结合在内蒙古上海庙一号矿井对回风立井冻结压力和水压力的监测结果,归纳出立井基岩冻结井筒外壁冻结压力和内壁水压力的理论计算公式,为我国西部矿区立井基岩冻结井筒的设计和施工提供了借鉴。Based on the design examples of bedrock freezing shafts in the mining areas of western China,combined with the monitoring results of freezing pressure and water pressure in the return shaft of Shanghaimiao №1 Mine,the calculation formulas of outer wall freezing pressure and inner water pressure of bedrock freezing shaft were summarized. The research can provide reference for the design and construction of bedrock freezing shaft in the mining areas of western China.
