论文提出了适合高温深井矿井建设期间的降温系统型式和降温设备类型，并提出了弥补风筒自压缩温升和传热温升的辅助降温措施；该降温系统及降温设备具有：能提供3℃低温冷冻水，通风阻力小，能净化风流，处理温差、焓差大，施工工期短，新增投资小等优点。针对赵楼矿地温及气象条件设计的降温系统，喷水室平均处理温差可达19.5℃-23.8℃，平均处理焓差可达48.4kj/kg-60.7kj/kg。同时根据实测结果总结得出了一系列可用于矿井建设期间降温系统设计及设备选择的基础数据；并利用MatLAB分析软件回归得出了喷水室喷水温度与风机出口送风温度之间、风筒温升与风机出口送风温度之间、工作面温度与送风温度之间的变化关系，以便供类似条件的矿井降温所借鉴。

This paper proposes the cooling system type and cooling equipment type which are deep mine with high temperature during the construction, and presents auxiliary cooling measures making up duct temperature rise since compression and heat transfer temperature rise. The cooling system designed against Zhaolou mine’s ground temperature and weather conditions, with its sprinkler room handling an average temperature difference up to 19.5～23.8 ℃，and the average enthalpy difference could reach 48.4～60.7 kJ/kg. At the same time, it gets a series of basic data used for mine construction during the cooling system design and equipment selection according to the measured results; Using the analysis software Matlab, it obtains the change relations between the temperature of sprinkler room and fan export supply air temperature, wind casing temperature rise and fan export supply air temperature, working face temperature and supply air temperature, used for the mine cooling which has the similar conditions.
