对祁东矿井人工冻土力学性能试验研究结果表明：祁东冻土冻结温度低、冻土强度小、膨胀性大、冻土在２４ ｈ 内应力松弛很快；三轴剪切试验中发现，在１～１０ ＭＰａ 围压条件下，冻土强度与围压几乎无关。试验结果被工程实践所证实，可为宿东矿区其它矿井建设提供依据。
Experimental results on the mechanical properties of the artificial frozen soil in Qidong Mine show that the freezing temperature of Qidong permafrost is low, the strength of permafrost is small and its expansibility is large. The stress relaxation in frozen soil is rapid within 24 h. In triaxial shear test, Under the confining pressure of 1 ~ 10 MPa, the strength of permafrost is almost independent of confining pressure. The test results are confirmed by the engineering practice, which can provide basis for other mine construction in Sundong mining area.
