由于地下深部作业环境的特殊性，如顶板冒落、岩爆和突水等地质灾害频发问题，对矿山安全性和稳定性的要求极高，而采用下向进路充填法对于控制地压活动和岩层移动具有显著效果。鉴于此，以非洲谦比希铜矿为案例，首先采用结构面数字识别系统，对矿体结构面进行了详细分析。结果表明：深部矿体结构面的发育情况对矿山的安全开采具有重要影响。结构面的高密度和小间距特征增加了岩体的破碎程度，增加了顶板崩落和采场不稳定性的风险。同时，对谦比希铜矿深部区域的力学行为和变形特性展开了数值模拟，通过优化承载层的结构和强度，可以有效控制采场的稳定性。模拟结果显示，承载层结构完好，能够承受上覆岩层的压力，采场稳定性较高。研究成果为深部矿山安全开采的提供了有效策略，特别是对于高风险的地质环境，提出了适应性强的开采方法和安全措施，这些策略对于提高深部矿山开采的安全性和效率具有重要意义。

Due to the unique challenges of deep underground mining environments, such as frequent geological disasters like roof fall, rock bursts, and water inrush, there is a high demand for enhanced safety and stability in mines. The use of downward roadway backfilling methods has shown significant effectiveness in controlling ground pressure activities and rock layer movement. In light of this, the Chambishi Copper Mine in Africa was selected as a case study. Initially, a digital structural plane identification system was employed to conduct a detailed analysis of the ore body structural planes. The findings indicate that the development of structural planes in deep ore bodies significantly impacts the safe extraction of minerals. The high density and narrow spacing of these planes increase the fragmentation of the rock mass, elevating the risk of roof fall and instability in mining areas. Additionally, numerical simulations were performed to study the mechanical behavior and deformation characteristics of the deep zones of the Chambeshi Copper Mine. By optimizing the structure and strength of the bearing layers, the stability of the mining area can be effectively controlled. The simulation results demonstrate that well-structured bearing layers are capable of withstanding the pressure from overlying rock strata, ensuring higher stability in the mining areas. These research outcomes provide effective strategies for the safe extraction of minerals in deep mines, particularly in high-risk geological environments. Adaptable mining methods and safety measures were proposed, which were of significant importance for enhancing the safety and efficiency of deep mining operations.
