中文摘要：

采用μCT225KVFCB高精度显微CT试验系统,利用CT衰减系数,从细观角度研究了自然状态下钙芒硝的空隙情况。研究表明：钙芒硝岩样的空隙度仅为0.59%~0.7%,等效空隙直径仅为1.11μm。这些研究结论对钙芒硝原位水溶开采的实施和控制具有非常重要的意义。

英文摘要：

The glauberite samples were scanned by high-precisionμCT225KVFCB microscopic CT test system.From the microscopic structure,the voidage of glauberite in a natural state was studied using CT attenuation coefficient.The results showed that the voidage of the glauberite samples was 0.59%~0.7%,and the equivalent void diameter was only 1.11μm.These results are very important for the implementation and control of the in-situ dissolution mining of glauberite deposit.
