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。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.
