| 中文摘要: |
| 淮南顾桥煤矿东风井采用冻结法施工，为了提供表土层冻结参数以进行矿井设计，本文对风井井筒孔检查孔所取土样进行了人工冻结的单轴抗压强度、冻胀性能以及结冰温度试验研究，得到了其应力—应变、冻胀力和结冰温度等参数，试验结果为淮南类似矿井建设提供了设计基础。 |

| To provide topsoil freeze parameters for mine design ,the Huainan Dongfeng wells of Guqiao Mine were Constructed by freezing. In this paper, air shaft bore hole by checking soil samples were artificially frozen uniaxial compressive strength，frost heave performance and the freezing temperature tests， obtained their stress - strain、heave forces and frozeing temperature ,and the test results，similar to mine construction for the Huainan Mine，Provided theory basis of design. |
