Aiming at the extraction challenges of high-grade ore bodies in deep fractured surrounding rock, the applicability of the drift filling mining method was explored using a copper-gold mine as the engineering background. Through core sampling, uniaxial compression and Brazilian splitting tests, combined with the Hoek-Brown and Mohr-Coulomb strength criteria, the key mechanical parameters of the surrounding rock and backfill were obtained. Subsequently, numerical simulations on overhand and underhand drift filling mining methods were conducted to analyze the displacement characteristics of the surrounding rock under corresponding support conditions, and scheme optimization was achieved by integrating technical and economic indicators. The results indicate that the overhand drift filling mining method is applicable to ore bodies with good to moderate rock mass stability, whereas the underhand drift filling mining method is more suitable for ore bodies featuring extremely fractured and highly unstable rock masses. For both drift filling mining methods, the total displacement of the surrounding rock remains relatively small; however, the displacement distributions differ due to variations between the roof and the floor. An economic comparison reveals that the underhand drift filling mining method incurs higher mining and filling costs (4.01 yuan/t higher than the overhand drift filling mining method), while its support costs are lower (0.313 yuan/t lower than the overhand drift filling mining method). Based on a comprehensive evaluation, the overall application of the overhand drift filling mining method is recommended, with the underhand drift filling mining method reserved exclusively for localized areas containing highly fractured surrounding rock.

针对深部破碎围岩高品位矿体开采难题，以某铜金矿为工程背景，探索进路式充填采矿法的适用性。通过钻孔取芯、单轴压缩与巴西劈裂试验，结合Hoek-Brown及Mohr-Coulomb强度准则，获取了围岩与充填体的关键力学参数。随后，开展了上向与下向进路式充填采矿法的数值模拟研究，分析相应支护条件下的围岩位移特征，并结合技术经济指标进行优选。结果表明：上向法适用于矿岩稳固性较好至中等的矿体，而下向进路法更适用于矿岩极破碎、稳固性极差的矿体；两种进路式充填采矿法的围岩总位移量均较小，但受顶底板差异影响，位移分布不同。经济性对比显示，下向法采充成本较高（较上向法高4.01元/t），而其支护成本较低（较上向法低0.313元/t）。综合考虑，推荐整体采用上向进路充填采矿法，仅在局部围岩高度破碎区域采用下向法开采。
