To investigate the influence of stope width and stoping sequence on the bearing capacity of panel pillars, this study takes the panel mining using the stage open-stope with subsequent backfill mining method in Sijiaying Iron Mine as the engineering background. The stress response and deformation failure characteristics of panel pillars under different stope widths and stoping sequences were analyzed, and the optimal mining scheme was selected. The research results are as follows. Firstly, stope width and panel stoping sequence jointly influence the stress response characteristics of panel pillars. Under different stoping sequences, both the maximum principal stress and the minimum compressive stress within the pillars exhibit an increasing trend as the stope width increases. Secondly, stope width and panel stoping sequence jointly influence the deformation failure characteristics of panel pillars. Under the same stoping sequence, both the displacement of the pillars and the volume of the plastic zone increase with the increase in stope width. Finally, under the same stope width, the displacement of the pillars and the volume of the plastic zone rank from high to low in the order of "from one side to the other" "from both sides to the center", and "from the center to both sides". Taking into account safety and production capacity of the stope, the optimal mining scheme for this mine has been determined to be a mining width of 20 meters and a mining sequence of "from the center to both sides".

为探究采场宽度与回采顺序对盘区间柱承载能力的影响,以司家营铁矿阶段空场嗣后充填采矿法盘区开采为工程背景,分析了不同盘区采场宽度和回采顺序下盘区间柱的应力响应与变形破坏特征,并选出最优回采方案。研究结果表明:采场宽度与盘区回采顺序共同影响着盘区间柱的应力响应特征,不同回采顺序下,随采场宽度增大,间柱内部最大主应力和最小压应力均呈现出增长趋势;采场宽度与盘区采场回采顺序共同影响着盘区间柱的变形破坏特征,相同回采顺序下,间柱位移量与塑性区体积均随采场宽度的增大而增大;相同的采场宽度下,间柱位移量和塑性区体积从高到低依次为“一侧推向另一侧”“两侧推向中央”“中央推向两侧”。综合考虑安全性与采场生产能力,最终确定该矿最优盘区采场回采方案为采场宽度为20 m、回采顺序为“中央推向两侧”。
