15111 working face of Huangyanhui Coal Mine in Shanxi Province was selected as the support of the actual project, and the stress distribution state and roadway deformation characteristics of coal pillar and solid coal under different coal pillar widths were analyzed in depth, aiming to realize the optimal design of the parameters of coal pillar excavation along the gob of the track channel in this working face. The lateral stress distribution law of goaf was deeply discussed, and the stress distribution of small coal pillar after goaf excavation was studied. At the same time, the distribution characteristics of vertical stress and horizontal stress during mining are comprehensively analyzed, and the specific values of vertical displacement and horizontal displacement in mining stage are precisely measured. The research results show that with the continuous increase of the width of coal pillar, the stress carried by coal pillar and solid coal increases correspondingly. At the same time, the increase of the width of coal pillar causes the deformation of the two sides of the tunnel to expand first and then shrink, and the deformation decreases further when the tunnel reaches a stable state. However, the deformation of the top plate and the bottom plate showed a gradually decreasing trend. Through research and analysis, the optimal design size of coal pillar in goaf excavation is optimized and determined. The research result will provide a key and reliable reference standard for the coal pillar maintenance of Huangyanhui Coal Mine and other similar projects, and effectively promote the improvement of the safety, stability and economy of the project, which has important value for promoting the technological progress in related fields.

选取山西黄岩汇煤矿15111工作面为实际工程依托,对不同煤柱宽度下煤柱及实体煤的应力分布状态以及巷道变形特征进行深度剖析,旨在实现对该工作面轨道顺槽沿空掘巷煤柱留设参数的优化设计。深入探讨工作面采空区侧向应力的分布规律,对沿空掘巷后小煤柱的应力分布情形进行研究,同时全面分析回采期间垂直应力与水平应力的分布特性,并精确测定回采阶段垂直位移与水平位移的具体数值。研究结果显示,随着煤柱宽度持续增加,煤柱与实体煤所承载的应力也相应上升。与此同时,煤柱宽度的增大致使巷道两帮变形呈现出先扩大后收缩的变化趋势,待巷道达到稳定状态后,变形进一步减小,而顶板和底板的变形则呈现出逐步递减的态势。通过研究与分析,精准优化并确定了沿空掘巷煤柱的最佳设计尺寸。这一研究成果将为黄岩汇煤矿以及其他类似工程的煤柱留设提供关键且可靠的参考标准,有力地促进工程在安全性、稳定性以及经济性方面的提升,对于推动相关领域的技术进步具有重要价值。
