Addressing the challenges of complex and variable boundaries, low ore recovery rates, extensive roof exposure areas, and a low degree of mechanization associated with high-altitude tourmalinite-type massive orebodies, this study systematically analyzed the occurrence characteristics of the orebody to facilitate safe, efficient, and green mining operations. Four technical mining schemes were proposed, and their respective advantages, disadvantages, principal technical and economic indexes were comprehensively evaluated. Consequently, the upward drift filling mining method was identified as the optimal extraction scheme. The maximum allowable exposed areas of the orebody and surrounding rock were determined using the Mathews stability graphical method. Coupled with numerical simulations, the distribution patterns of stress, vertical displacement, and plastic zones under varying drift dimensions were elucidated, establishing the optimal drift parameters as 5 m in width and 3.5 m in height. On-site industrial tests demonstrate that the maximum roof subsidence of the stope is 19.2 mm, with no occurrences of collapse. Furthermore, the ore loss and dilution rates are 3.2% and 3.5%, respectively, representing significant reductions of 8.8 and 8.5 percentage points compared with the shallow-hole shrinkage mining with subsequent backfill method. These findings establish a robust technical paradigm for analogous mines and propel the sustainable development of high-altitude mineral resources.

针对高海拔电英岩型厚大矿体边界复杂多变、矿石回采率低、采场顶板暴露面积较大和机械化程度较低等问题，为实现安全高效绿色开采目标，系统剖析了电英岩型厚大矿体的赋存特征，提出了4种采矿技术方案，对比了各方案的优缺点、主要技术指标及经济效益指标，最终确定上向进路充填采矿法作为最优开采方案。基于Mathews稳定性图解法，得到了矿体、围岩的最大允许暴露面积。结合数值模拟，揭示了不同进路尺寸下应力、竖向位移和塑性区的分布规律，确定了最佳进路参数：进路宽度为5.0 m，高度为3.5 m。现场工业试验表明，采场顶板最大下沉量为19.2 mm，无垮塌现象；矿石损失率为3.2%、贫化率为3.5%，较浅孔留矿法嗣后充填采矿法降低了8.8个百分点和8.5个百分点，效果显著。研究结果为类似矿山提供了技术范式，推动了高海拔矿产资源的可持续开发。
