    Stability control of open stopes in high-stress deep mining: a structural parameter design methodology based on the improved mathews stability graph method by Zi-Bin Li, Zi-Bin Li, Deng-Pan Qiao, Deng-Pan Qiao, Tian-Yu Yang, Tian-Yu Yang

    Published 2025-06-01
    “…IntroductionWith the depletion of shallow mineral resources and surging demand for deep mining, metal mines in China have generally entered the kilometer-depth mining stage, confronting challenges in stope stability caused by high ground stress, elevated rock temperatures, high seepage pressure, and intense mining disturbances (“three highs and one disturbance”).MethodsTaking the Dahongshan Copper Mine (800–1000 m depth) as a case study, this paper proposes an enhanced design methodology for structural parameters of deep open stopes to address the limitations of the traditional Mathews stability graph method in 3D mechanical characterization, dynamic evolution analysis, and model generalization.ResultsFirst, an improved stability graph model was developed by refining hydraulic radius calculations through cross-sectional collaborative analysis and establishing quantifiable zoning thresholds for span and exposure area based on geological variations between eastern and western ore sections. …”
