摘　　要：随着矿井开采深度的不断提高,高温矿井掘进作业面热害问题日益凸显,如何有效地治理热害问题具有重要的意义。利用Fluent流体力学软件对掘进作业面降温效果进行模拟研究,通过设计新型局部降温系统,分析局部制冷-隔热层耦合降温效果,着重分析不同工况下隔热层导热系数、厚度以及空气夹层厚度对降温效果的影响。研究结果表明:导热系数由0.024 W/(m·K)增加到1.0 W/(m·K),降温幅度减少了1.4 K;综合考虑隔热成本和降温效果后,选择隔热层厚度0.1 m和空气夹层厚度90 mm时,制冷通风-隔热层耦合降温效果良好。本文为高温矿井有效降温提供参考价值,同时也为矿井环境的营造提供数据支持。With the continuous improvement of mining depth,the problem of thermal damage in high-temperature mine excavation faces has become increasingly prominent.It is of great significance to effectively control the problem of thermal damage.The cooling effect of excavation face was simulated by Fluent fluid dynamics software,and a new type of local cooling system was designed to analyze the cooling effect of local cooling-insulation coupling.The influence of thermal conductivity,thickness of thermal insulation layer and thickness of air interlayer on the cooling effect was analyzed under different working conditions.The results showed that the thermal conductivity increased from 0.024 W/(m·K)to 1.0 W/(m·K),and the temperature drop range was reduced by 1.4 K.After comprehensively considering thermal insulation cost and cooling effect,when the thickness of the thermal insulation layer was 0.1 m and the thickness of air interlayer was 90 mm,the coupling cooling effect of refrigeration ventilation and the insulation layer was good.It provides reference value for effective cooling in high-temperature mines,and also provides data support for the creation of mine environments.
