Taking Dahongshan Iron Mine as the engineering case, the study on the treatment of hidden goafs in open-pit slopes was carried out by combining theoretical analysis with numerical calculation. According to the relationship between goaf morphology and open-pit boundary, a treatment scheme of "blasting of goafs inside the boundary and filling of goafs outside the boundary" was proposed. The safety thickness of the goaf roof was determined, the progressive failure mode of the slope above the goaf was revealed, the treatment scope of goaf filling and the compressive strength threshold of the filling body were obtained, and the stability of the open-pit slope after goaf treatment was evaluated. The results indicate that the safety thicknesses of the goaf roofs inside and outside the open-pit boundary are 20-30 m and 20-25 m, respectively. The slope containing hidden goafs has successively experienced the failure processes of tensile cracking at the slope rear edge, progressive failure of goafs, local slope collapse, and large-scale slope instability. The filling treatment range for Layer Ⅱ and Layer Ⅲ goafs is 30 m from the slope side, and the compressive strength of the filling body should reach 20 MPa. After the filling treatment of goafs outside the open-pit boundary, the shear strain of the slope rock mass is reduced and transferred to the interior of the slope, and the safety factor of the slope can meet the stability requirements.

以大红山铁矿为工程案例，采用理论分析与数值计算相结合的方法，开展露天边坡隐伏采空区治理研究。依据采空区形态与露天境界的关系，提出了“境界内空区爆破+境界外空区充填”的治理方案。确定了采空区顶板安全厚度，揭示了采空区上部边坡的渐进破坏模式，得到了采空区充填治理范围与充填体抗压强度阈值，评价了采空区治理后的露天边坡稳定性。结果表明：露天境界内、外空区顶板安全厚度分别为20~30 m与20~25 m； 含隐伏采空区的边坡先后经历了边坡后缘拉裂、采空区渐进破坏、边坡局部坍塌、边坡大范围失稳的破坏过程； 第Ⅱ、Ⅲ层采空区充填治理范围为距离边帮30 m，且充填体抗压强度需达到20 MPa。境界外采空区充填治理后，边坡岩体的剪应变降低且向边坡内部转移，边坡安全系数可满足稳定性要求。
