为保障浅埋深、大断面巷道的围岩稳定，以黄山煤业五采区辅运上山为研究背景，通过巷道顶板钻孔窥视，分析了巷道顶板各岩层节理裂隙及厚度变化；基于自然平衡拱理论，计算了巷道关键支护参数，给出了浅埋大断面巷道支护方案；通过数值模拟分析了支护方案下围岩塑性区分布、围岩应力、围岩位移特征。矿压监测结果表明，该支护方案下巷道围岩变形在安全范围内，巷道整体支护效果较好。

 To ensure the surrounding rock stability of shallow buried large section roadway, the auxiliary haulage road in the No. 5 mining area of Huangshan Mine was selected as the study area. The joint fissures and thickness variations of the roof strata were analyzed using borehole observations. Based on the natural equilibrium arch theory, the key support parameters were calculated, and a support scheme for shallow buried large section roadway was proposed. Numerical simulations were conducted to analyze the distribution of the plastic zone, stress, and displacement characteristics of the surrounding rock under the support scheme. Mine pressure monitoring results indicated that the deformation of the surrounding rock remained within safe limits, demonstrating the overall effectiveness of the support scheme.
