摘　　要：针对深部金属矿采场热害问题,利用Fluent软件建立了金属矿采场通风降温数值模型,并将数值模拟结果与采场通风降温实验数据进行对比,以验证模型的有效性。分别对不同风温和风速下的采场降温状况进行数值模拟,得到了不同风速和风温下采场内的温度场和速度场分布云图;以采场散热负荷为评价指标,对比得到了风温和风速对采场降温的影响规律。Aiming at the problem of heat damage in deep metal mine stope,the numerical model of ventilation and cooling in metal mine stope is established by using Fluent software,and the numerical simulation results are compared with the experimental data of ventilation and cooling in stope to verify the effectiveness of the model.The numerical simulation of stope cooling under different wind temperature and wind speed is carried out respectively,and the distribution nephogram of temperature field and velocity field in stope under different wind speed and wind temperature is obtained.Taking the heat dissipation load of stope as the evaluation index,the influence law of wind temperature and wind speed on stope cooling is obtained.
