导热系数对于分析岩石导热特性、热传导规律研究具有重要现实意义,也是冻结法施工穿越围岩重要热物理参数。导热系数与岩石内部矿物成分、微观结构等密切相关,但关于该领域研究较少,具体微观结构对导热系数影响效应研究不系统。基于此,以新庄煤矿白垩系地层富水砂岩为研究对象,现场采集具有代表性的中粒砂岩、粗粒砂岩进行室内试验。首先,对两种砂岩展开常温饱水导热系数测试,获得各自对应的导热系数范围值;而后,分别展开X光衍射、扫描电镜(SEM)等微观测试试验,获得两种砂岩各自对应内在矿物组分及结构,并对内在矿物成分的导热特性进行了系统分析;最后,结合晶格振动理论,分析了砂岩导热系数与微观结构的关系;研究结果表明:饱水白垩系砂岩的热导率大小主要是取决于岩石骨架和间隙液体的热导率。由于白垩系砂岩的孔隙度低,白垩系砂岩的岩石骨架的导热率大小取决于岩石的矿物成分。
