五凤煤矿煤巷具有典型的节理化、遇水膨胀、易软化等物理特征,遇水之后突出地表现为非线性大变形、显著流变的工程特点,本文结合1610回风顺槽围岩现状,应用了X射线衍射对围岩岩性进行分析、对巷道表面进行了电镜微观结构扫描分析,分析可知该巷道岩性为典型的吸水膨胀型软岩,为下一步针对岩性设计支护方案提供理论基础。
五鳳煤礦煤巷具有典型的節理化、遇水膨脹、易軟化等物理特徵,遇水之後突齣地錶現為非線性大變形、顯著流變的工程特點,本文結閤1610迴風順槽圍巖現狀,應用瞭X射線衍射對圍巖巖性進行分析、對巷道錶麵進行瞭電鏡微觀結構掃描分析,分析可知該巷道巖性為典型的吸水膨脹型軟巖,為下一步針對巖性設計支護方案提供理論基礎。

Wufeng coal mine roadway is charactered with physical features such as typical jointed, water swelling, and easy softening,and will be ergineeringly featured as nonlinear large deformation and significant rheology. In combination with the current situation of 1610return air roadway surrounding rocks, this paper carries out electronicrostructure scanning analysis on the roadway surface through surrounding rock features by use of X-ray diffraction, which indicates the typical water swelling and expansion characters, and provides theoretical basis for further lithology design supporting plan.
