摘　　要：针对特厚表土层立井冻结方案的选择尚无理论依据的现状,采用理论计算和数值模拟相结合的分析方法,获得了丁集矿冻结温度场分布规律和冻结壁厚度等重要冻结参数。实践表明,该设计方案能较好地满足现场工程实践的要求。In view of the status ,that there is not theoretical basis for project determination of shaft lining freezing in deep alluvium, in the paper a method which combines the finite element numerical simulation with theoretical calculation was brought forward, by which some important parameters, such as temper-ature field distribution regularity in frozen alluvium and thickness of frozen wall in Dingji Coal Mine were obtained. Practice indicated that the method can satisfy practical engineering demands.
