摘　　要：介绍了对冻结深度为702 m、表土厚度583.1 m的郭屯煤矿副井危险的深厚粘土层的数值模拟,模拟了冻结壁温度场、平均温度、冻结壁厚度以及井帮温度,结果与实测相符。预测了井筒冻结情况的发展,指导工程的下一步施工。其计算方法和结果为今后类似工程的施工提供了重要的指导作用。This paper introduces numerical simulation of Guotun Coal Mine where freezing depth is 702 meters and topsoil layer depth is 583.1 m with dangerous deep clay layer, simulates frozen wall temperature site, mean temperature and frozen wall thickness as well as temperature of well wall, the result close to the temperature of actual measurement. The purpose is to foresee the development of frozen condition and to guide next step of construction. Moreover, it plays an instructional function for similar engineering.
