摘要
在分析龙口矿区2号煤层顶底板粘土岩的物质组成、微结构和物化特性的基础上，讨论了粘土岩的膨胀特性对巷道稳定性的影响，进而指出了本研究在巷道工程应用中的意义。
Based on the study of the dineral composition, the micro-structure and the physico-chemical properties of claystone in the roof and the floor for No. 2 seam in Longkou Coal Mining Area, the paper has analysed the influence of claystone expansive properties on the stability of a tunnel, then the significance of this study in tunnel engineering practice has been pointed.
