摘　　要：文章在详细分析国内外矿井热害治理理论和措施的基础上，总结出高温矿井热害的根源，归纳了热害治理的技术方法，提出利用极细雾粒相变的吸热来进行降温的方法，并运用流体力学软件FLUENT对降温设备进行数值模拟，结果表明：30℃的热风经过设备的降温后变为20～22℃的风流，温度下降了8～10℃，符合矿井降温的要求。Based on in detail analysis on the mine thermal disaster control theory and measures at home and abroad, the paper summarized the sources of the mine thermal disaster in the high temperature mine, concluded the technical methods of the mine thermal disaster control and provided the mine cooling method with the thermal adsorption with the phase transformation of the ultra fine fog particles. The fluid mechanics software FLUENT was applied to the numerical simulation of the cooling equipment. The results showed that the hot air with a temperature of 30℃ could be changed to an air flow with a temperature of 20 - 22℃ after the air cooling with the equipment and the air temperature reduced to 8 - 10℃ could meet the requirements of the mine temperature cooling.
