| 摘 要： | 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。

| Abstract: | By experim ents, itis found thatthe properties offrozen soilin Qidong Mine include low -freezing-tem perature, low -intensity, high-sw elling, quick-stresses-laxation in 24 hours, and the strength is notaffected alm ostly by confining pressure (in 1 to 10 MPa). The resultoftestisconfirm ed in practice, and can be taken fora basisofdesign in Sudong m ining area. |
