To address the challenges such as potential large-scale surface subsidence caused by mining the hung-up orebody in the triangular ore belt of a certain silver-lead-zinc mine, two overall mining sequence plans were proposed based on the site engineering geological conditions. Plan I involves treating the goaf and hung-up ore zone prior to ore extraction, while Plan II involves extracting the ore first followed by treatment of the goaf and hung-up ore zone. A geological model was constructed by combining CAD, 3DMine, and MIDAS, and numerical simulation was subsequently employed to compare the distributions of the stress field, displacement field, and plastic zone at various mining stages for these two plans. The results indicate that Plan I is more favorable for controlling ground pressure and ensuring stability in both the stope and the hung-up ore zone during mining operations, while also reducing resource wastage. Based on the numerical simulation results and mining technical conditions, a coordinated mining scheme involving the initial construction of an artificial false roof (and floor) followed by extraction from the bottom was proposed, and the construction scheme for the artificial false roof (and floor) was determined. A prediction model for the settlement of the artificial false roof was developed using the random forest algorithm to continuously ensure the safety of hung-up ore extraction in the area. The results of the industrial-scale trial show that the extraction rate of the hung-up ore exceeds 80%, generating approximately 5 million yuan in profit.

针对某银铅锌矿三角矿带存窿矿体回采会导致大面积的地表塌陷等难题，基于现场工程地质条件，提出了两组整体回采规划方案，即预先处理空区存窿矿区域后回采矿体方案和先采矿体后处理空区存窿矿区域方案，并利用CAD-3Dmine-MIDAS联合构建了地质模型，进而采用数值模拟方法比选两组规划方案对应模型各回采阶段应力场、位移场及塑性区分布情况，结果表明，规划方案Ⅰ更有利于回采作业过程中的采场和存窿矿区域地压及稳定性控制，减少资源浪费。根据数值模拟结果和开采技术条件，提出了先筑假顶（底）、底部协同回采方案，确定了人工假顶（底）的构筑方案，结合随机森林算法构建人工假顶顶板沉降量预测模型，持续保障区域内存窿矿石回采的安全。工业试验结果表明，存窿矿的回采率达到80%以上，创造约500万元的利润。
