金陶金矿井下岩体掘进过程中存在的地压问题、掌子面及成形巷道均出现冒顶片帮现象，尤其是破碎区域巷道冒顶片帮出现概率较高。通过数值模拟和现场应用等方式，对不同等级顶板支护效果进行评价，结果表明：金陶金矿井下岩体质量较好，但巷道掘进过程中易在拱肩位置产生应力集中；通过对拱肩进行加强支护，并对不同等级顶板采取相应的支护方式和参数，在生产过程取得了良好效果。  

During underground rock excavation at the Jintao Gold Mine, ground pressure issues have led to occur-rences of roof caving and sidewall spalling at the tunnel face and formed roadways, particularly in fractured zones where roof caving and sidewall spalling are more frequent. This study evaluates the support effectiveness for roofs of varying classes using numerical simulation and field application. Results indicate that although the underground rock mass quality at the Jintao Gold Mine is generally good, stress concentration tends to occur at the arch shoulder during roadway excavation. By reinforcing the arch shoulder and adopting appropriate support methods and parameters for roofs of varying classes, favorable outcomes have been achieved in the production process.
