| 摘 要： | 从遇水作用后的结构状态稳定性角度,山东巨野煤田3煤顶底板软岩分为浸水碎解、泥化(Ⅰ类)、浸水裂解(Ⅱ类)和不崩解(Ⅲ类)3种水稳类型。应用X衍射和电镜扫描分析结果表明,这3种类型软岩的全岩物质成分、所含粘土矿物种类及含量都比较接近,但在微结构形态却差异明显,反映出其水稳性主要受控于微观结构。

| Abstract: | In light of the stability of texture state of the soft rocks of coal measure in water,the roof and floor of soft rocks of third-coal in Juye Coal Field may fall into three water stability types: soggy smashed and argillitized(type I),soggy splitting(type II) and nondisintegration(type III).Through X-ray diffraction and electron microscope scanning,it is demonstrated that the bulk-rock mass composition,clay mineral types and contents are very close for the above three soft rocks,but are very different in micro texture state,reflecting their water stability are dominated by microtexture. |
