To achieve safe mining in the near-shaft area of steeply inclined thin orebody, a steeply inclined thin gold mine was taken as the engineering background. Combined with the geological conditions of the mine, the applicable mining method was preliminarily selected, and the primary selection scheme was optimized by using the analytic hierarchy process and fuzzy decision theory. FLAC3D numerical simulation was used to analyze the shaft stability during the mining process in the newly added recoverable near-shaft area. The results show that the upward drift filling mining method is the optimal mining scheme for the newly delineated area of the shaft safety pillar. Compared with ascending mining, descending mining reduces the extreme value of the maximum unbalanced force in the stope by 15%-20%, effectively alleviates the local stress concentration in the ore body, and helps restrain ground pressure activities and control shaft displacement. The optimized mining sequence gradually releases stress and creates a favorable stress environment for the stope. The filling body plays a key supporting role, and their synergistic effect significantly enhances the overall stability of the stope and effectively inhibits rock mass failure and propagation. The on-site monitoring results of the shaft indicate that after adopting the descending mining scheme, the maximum compressive deformation of the main shaft is 0.049 mm/m, and the maximum tensile deformation of the blind shaft is 0.151 mm/m, both values meet the requirements specified in safety regulations (2.0 mm/m). The field industrial test results show that the upward drift filling mining method has good safety and economic benefits, the resource recovery rate is increased to 95%, realizing the coordinated optimization of safety, economic benefit and resource recovery.

为实现急倾斜薄矿体近井筒区域的安全回采，以某急倾斜薄金矿为工程背景，结合矿山地质条件初步筛选出适用的采矿方法，并运用层次分析法与模糊决策理论对初选方案进行优选。采用FLAC3D数值模拟，分析了新增可采的近井筒区域回采过程中的井筒稳定性。结果表明：上向进路充填采矿法为井筒保安矿柱新圈定区域的最优回采方案；相较于上行式回采，下行式回采使采场最大不平衡力极值降低15%~20%，有效缓解了矿体的局部应力集中，有助于抑制地压活动和控制竖井位移；优化后的回采顺序通过逐步释放应力，为采场创造了良好的应力环境；充填体发挥了关键支撑作用，二者协同作用显著提升了采场的整体稳定性，并有效抑制了岩体破坏与扩展；竖井现场监测结果表明，采用下行式回采方案后，主竖井的最大压缩变形量为0.049 mm/m，盲竖井的最大拉伸变形量为0.151 mm/m，均满足安全规程要求（2.0 mm/m）。现场工业试验结果表明，上向进路充填采矿法兼具良好的安全性与经济效益，资源回采率提高至95%，实现了安全、效益与资源回收的协同优化。
