我国内蒙地区矿井建设普遍采用冻结法凿井，井筒均需穿越侏罗系地层，但该地层物理力学性能较华东地区第三系地层差异较大，目前对侏罗系地层物理力学特性研究不够，急需在实验室内开展该方面研究。通过对某在建矿井侏罗系地层岩石进行物理力学性能试验，掌握鄂尔多斯矿区侏罗系地层基本物理性能指标，以及低温条件下力学特性，为该地区冻结井筒冻结设计提供依据。

Inner Mongolia Area of China, Mine Construc-tion general use Freezing Method when shaft is sinking. All of shaft needs cross Jurassic Formation, but physical and mechani-cal properties of the formation make a great difference to tertiary stratum in east China. At present, the research of physical and mechanical properties is inadequate at Jurassic Formation, so need for this aspect research in laboratory is urgent. This paper by research of physical and mechanical properties at Jurassic Formation of a building coal mine, mastered basic physical properties in Jurassic Formation at Ordos area, and mechanical behavior under low temperature. The result of this paper provid-ed basis for frozen shaft at Ordos area.
