There are many residual pillars and top pillars under the condition of filling body enveloping in a high-grade iron mine. In order to recover high-grade iron ore resources as much as possible, a recovery scheme of residual pillar and top pillar was studied. Comparative analysis of the technical and economic indexes between the downward drift filling mining method and the sublevel filling mining method was conducted. And the sublevel filling mining method with simple mining process, high mining intensity and low production cost was selected as the best mining method for residual pillar recovery. Based on the selected mining method, numerical simulation was used to analyze the displacement, stress, and plastic zone distribution of the surrounding rocks and filling materials in the mining area under different structural parameters of mining room. Optimization research was conducted on the structural parameters of mining room under the mining of the 606# inter pillar and the top pillar at -525 m sublevel. The simulation calculation results show that the optimal structural parameter scheme for the mining room under the recovery of 606# inter pillar is a mining room length of 30 m without leaving a top pillar. The maximum displacement of the mining room roof in this scheme is 50.00 mm, and the volume of plastic zone of roof is the minimum, which is 1 534.55 m3. The optimal structural parameter scheme for the mining room under the recovery of top pillar is that the spans of the first and second step mining rooms are 8 m and 10 m, respectively, and the length is 25 m. The maximum displacement of the mining room roof in this scheme is 57.64 mm, and the volume of the plastic zone per unit area of the roof is small, which is 1.02 m3. There is no obvious connection in the plastic zone of the filling body inside the mining area.

某高品位铁矿山局部残留多处由充填体包覆的间柱及顶柱。为尽可能回收高品位铁矿资源,对残留间柱及顶柱的回采方案进行了研究。通过对下向进路充填采矿法与分段充填采矿法进行技术经济指标对比分析,选择回采工艺简单、开采强度高、生产成本低的分段充填采矿法作为回采残留矿柱的最佳采矿方法。根据选择的采矿方法,通过数值模拟手段,分析不同矿房结构参数下的采场围岩及充填体位移、应力、塑性区分布,对606#间柱以及-525 m分段位置顶柱回采的矿房结构参数进行了优化研究。模拟计算结果表明,回采606#间柱的最佳矿房结构参数方案是矿房长度为30 m、不留设顶柱,此方案的矿房顶板位移最大值为50.00 mm,顶板塑性区体积最小,为1 534.55 m3;回采顶柱的最佳矿房结构参数方案是一、二步骤矿房的跨度分别为8 m和10 m、长度为25 m,此方案的矿房顶板位移最大值为57.64 mm,顶板单位面积塑性区体积较小,为1.02 m3,采场内部充填体塑性区无明显的贯通。
