| description | This study, based on a case from the 1314 working face of Xiaoyun Coal Mine, provides an in-depth analysis of the stress and velocity field characteristics of waterproof coal pillars under different porosities during water inrush events. The research emphasizes the significant impact of water inrush on the stress field distribution of coal pillars. Simulation results, validated by field data, reveal that the highest stress concentration occurs on the side of the coal pillar adjacent to the goaf, with the stress distribution under water inundation conditions exhibiting greater irregularity. The findings not only enhance the understanding of stress variations in coal pillars during water inrush events but also offer valuable insights for coal pillar design and monitoring strategies. This research provides critical theoretical support and technical guidance for the safe design and dynamic monitoring of water inrush disaster prevention in coal mines. |
