外文摘要: |
To address the problems of surrounding rock deformation and support in the drivage of steeply inclined thick coal seams, taking the B3 roadway at the +400 level of Wudong Coal Mine as the research background, this study adopts rock mechanics experiments, theoretical analysis, numerical simulation and field monitoring methods to systematically study the mechanical response characteristics and failure laws of coal samples under different bedding angles. The deformation mechanism of the surrounding rock in the drivage of steeply inclined thick coal seams is revealed, and a deformation - control and impact - resistant support scheme is proposed and implemented in engineering practice. The main conclusions are as follows: |
