中文摘要：
大台井-10m水平第二分层3槽煤采用急倾斜厚煤层分层开采方法，针对顶板巷道的地质条件，运用X射线衍射分析和扫描电镜SEM微观结构分析，掌握了围岩性质，经过FLAC模拟，选择合理的支护方案——锚网索联合支护方案进行支护，经现场实践检验，控制了围岩变形，证明支护效果显著，保证了生产的正常进行。
英文摘要：
Steep inclined thick seam slicing method was applied on the second layer of -10m level Datai mine. With the X-ray diffraction analyses and the SEM microstructure analyses, the characteristic of enclosing rock was known. The best support program, bolt-mesh-anchor combined support, was selected. The practices showed that the rock deformation was effectively controlled. The support system endured the safety production; its support effect was obvious.
