Against the backdrop of panel mining utilizing the stage open stoping with subsequent backfill method during the transition from open-pit to underground mining at Sijiaying Iron Mine, three stope mining sequence schemes were proposed: "from one side to the other" "from the center to both sides", and "from both sides to the center". A numerical simulation approach was employed to investigate the stress field distribution characteristics, displacement variations, and plastic zone propagation laws of the surrounding rock in the panel stope under different mining sequences. Ultimately, the "from the center to both sides" sequence was determined to be the optimal mining scheme for this mine. The results are shown as follows. Firstly, across the three mining schemes, the compressive stress following stress release, the tensile stress, and the maximum internal displacement within the surrounding rock consistently exhibit a trend of "from the center to both sides" < "from both sides to the center" < "from one side to the other". Secondly, under the "from the center to both sides" scheme, the compressive stress and maximum tensile stress of the surrounding rock following stress release are 1.58 MPa and 0.35 MPa, respectively, with a maximum internal displacement of 37.765 mm; these values are universally superior to those of the other two schemes. Finally, following panel extraction, the total volume of the plastic zone in the surrounding rock, and the volume ratio between the tensile plastic zone and the total plastic zone, exhibit the same variation law as the surrounding rock stress field and displacement field. Specifically, the "from the center to both sides" scheme yields a total plastic failure volume of 34.73×10⁴ m³ and a tensile plastic zone ratio of 60.60%, both of which outperform the alternative schemes. These findings hold significant implications for guiding the design and future production of the mine during its transition from open-pit to underground operations.

以司家营铁矿露天转地下开采阶段空场嗣后充填采矿法盘区开采为背景，提出了“一侧推向另一侧”“中央推向两侧”和“两侧推向中央”3种采场回采顺序方案。采用数值模拟方法，研究了不同回采顺序下盘区采场围岩的应力场分布特征、位移变化与塑性区扩展规律，确定“中央推向两侧”为该矿的最优回采顺序方案。结果表明：3种回采顺序方案下，盘区采场围岩应力释放后的压应力值、围岩的拉应力和围岩内部产生的最大位移值，均呈现出“中央推向两侧”<“两侧推向中央”<“一侧推向另一侧”的变化规律；在“中央推向两侧”回采顺序下，围岩应力释放后的压应力值为1.58 MPa、最大拉应力为0.35 MPa，围岩内部产生的最大位移值为37.65 mm，均优于其他方案；盘区开采后，围岩内总塑性区体积、张拉塑性区与总塑性区的体积比，表现出了与围岩应力场和位移场相同的变化规律，其中“中央推向两侧”方案下，围岩塑性破坏区的总体积为34.73×10⁴ m³，张拉塑性区体积占比为60.60%，均优于其他方案。研究结果对指导矿山露天转地下开采设计及生产具有重要意义。
