| 摘 要： | 随着矿井开采深度的增加,井下地温不断升高,矿井高温问题日益突出,矿井降温已经成为保障矿山安全生产的一项重要工作.应用井巷冷却圈理论,建立了利用矿山浅部岩层的低温效应预冷矿井入风流的热交换模型并推导出了该模型在一般情况下的解析解,并用金洲矿业集团金青顶矿区地温预冷井巷的实测数据对该模型进行了分析验证.

| Abstract: | With the increase of the depth in mines, the underground geotemperature increases unceasingly, and the problem of high temperature becomes more and more serious, and mine cooling has become an important task to ensure mine＇s safe production. By means of the cooled zone theory, a heat exchange model of precooling inlet airflow utilizing the low temperature effect of shallow terrain is established, and the analytical solution under normal circumstances is got, then the model is analyzed and validated by use of geotemperature precooling data measured in Jinqingding Mine Area of Jinzhou Mining Group. |
