Aiming at the high temperature-pollution coupling problem caused by complex diagonal ventilation in the large-scale mining of dense stope groups of deep well in metal mines, a four-dimensional analysis framework of "orthogonal test and control variable method, Fluent numerical simulation, Ventsim ventilation solution and multiple linear regression" was constructed, which revealed the key role of the selective closing of the wind door in the cross-cut in the reconstruction of the wind path. The results show that the importance of the influence of various factors on the temperature field of the ore drawing roadway is as follows: the surrounding rock temperature>the inlet wind velocity of the 2^# cross-cut>the inlet wind temperature>the inlet wind velocity of the 0^# cross-cut. The optimization scheme of closing the wind door of 0^# cross-cut roadway and constructing 2^# inlet and 0^# outlet through the wind path is proposed. The scheme increases the wind volume of the ore drawing roadway from 10.8 m³/s to 30.7 m³/s, increases the regional wind speed from 0.1 m/s to 0.6 m/s, and reduces the average temperature in the roadway to 26.03 ℃. The optimization scheme effectively solves the problem of local crosswind, improves the efficiency of pollutant discharge, and improves the underground working environment. It provides a theoretical basis and engineering practice example for the regulation of "precise minimally invasive surgery" for the ventilation system of dense stope groups in similar deep wells.

针对金属矿深井大盘区密集采场群的规模化开采中，复杂角联通风引发的“高温-污染”耦合难题，构建了“正交试验与控制变量法、Fluent数值模拟、Ventsim通风解算及多元线性回归”的四维分析框架，揭示了穿脉巷风门选择性关闭对风路重构的关键作用。结果表明：各因素对出矿巷温度场的影响重要程度为围岩温度>2^#穿脉入风风速>入风温度>0^#穿脉入风风速；提出关闭0^#穿脉风门、构建“2^#进、0^#出”贯穿风路的优化方案，该方案使出矿巷风量由10.8 m³/s增至30.7 m³/s，区域风速由0.1 m/s 增至0.6 m/s，巷道内平均温度降至26.03 ℃。优化方案有效解决了局部串风问题，提高了污染物排放效率，改善了井下作业环境，为类似深井大盘区密集采场群通风系统“精准微创手术式”的调控提供了理论依据与工程实践范例。
