In view of the following mining technical challenges in underground mine operations: some stopes are laid out within the broken oxidation zone, giving rise to roof caving and sidewall collapse during production, in addition, ore caving trenches are reserved at the bottom of sublevel medium-deep hole stopes to facilitate ore drawing, which results in the failure of effective recovery of the triangular ore pillars at the stope bottom after mining completion due to the poor quality of backfill materials, thus causing enormous waste of mineral resources. A polymetallic mine was selected as the research object, through field investigation, theoretical analysis and reference to the experience of similar mines, a combined support scheme of shotcrete-bolt-mesh with long anchor cable grouting was proposed to pre-reinforce the roof of the stope to ensure the safe mining of ore in the range of broken oxidation zone. Meanwhile, the medium-deep hole blasting technology was optimized, and the goal of non-trench simultaneous row recovery of bottom pillars was achieved by supplementing short holes. The industrial test results show that after the adoption of the optimized scheme of "pre-controlled roof reinforcement + supplementary short-hole simultaneous row recovery of bottom pillars", the stope roof stability and ore resource recovery rate are significantly improved, the comprehensive production capacity of stopes increases by 21.54% compared with the original scheme, and the loss rate and dilution rate are reduced to 8%, which can be popularized and applied in the underground production area.

针对矿山井下部分采场布置区域位于破碎氧化带范围内，在生产过程中出现的顶板垮落和侧帮垮塌情况，以及分段中深孔采场底部留有落矿堑沟便于出矿，导致采场完成生产后，底部三角矿柱受较差充填体质量影响无法有效回采，造成资源极大浪费等开采技术难题。以某多金属矿为研究对象，通过现场调研、理论分析及参考同类型矿山经验，提出了喷锚网加长锚索注浆联合支护方案，对采场顶板进行预加固支护，以确保破碎氧化带范围内矿石的安全开采；同时优化了中深孔爆破工艺，通过补充浅孔实现无堑沟同排回采底柱的目的。工业试验结果表明：采用“预控顶加固+补充浅孔同排回采底柱”的优化方案后，采场顶板稳定性及矿石资源回采率得到了显著提升，采场综合生产能力较原方案提高了21.54%，损失率及贫化率降低至8%，可在井下生产区域内推广应用。
