摘　　要：李粮店煤矿主井深771.2 m,穿过深厚冲积层和深厚含水基岩。该矿通过开展技术研究,提出了适合矿井特点的全深冻结方案设计、冻结段掘砌施工工艺等,实现了安全、快速施工。简要介绍了技术研究的相关情况和效果,对我国深厚冲积层和含水基岩全井深冻结井壁设计施工等问题进行了探讨。The depth of main shaft in Liliangdian coal mine is 771.2 m, which passes through the deep alluvial and deep bedrock aqui- fer. Through technical research, the whole design for deep freeze, frozen sections dig puzzle construction technology was proposed for the characteristics of the mine, which achieved a safe and rapid construction. The paper briefly describes the relevant research and ef- fectiveness. Shaft design and construction of deep freezing in deep alluvium and bedrock water of China were discussed.

关 键 词：深厚冲积层 深厚含水基岩 全深冻结 快速施工
