针对园子沟矿井1012102采煤工作面高温热害问题，采用喷雾降温实验确定最佳喷雾压力和喷嘴雾化参数，数值模拟分析不同喷雾温度和喷雾间距对降温效果的影响，并采用线性回归方法分析了采用喷雾前后人体的舒适度。结果表明：当综采工作面中喷雾系统采用组间距10 m，水温为286 K，压力6 MPa的参数时，单组峰值温度与常规通风方式的温差达到了1.3 ℃。在现场应用后，工作面人行道侧大部分区域的温度低于26 ℃，最高气温降至27 ℃以下，最低温度低至24.7 ℃，有效实现了区域降温。

For the problem of high temperature heat damage at 1012102 working face in Yuanzigou Mine, the best spray pressure and nozzle atomization parameters are determined by using the method of spray cooling experiment. The numerical simulation method is used to simulate and analyze the influence of different spray temperature and spray spacing conditions on the cooling effect, and the comfort of human body before and after spray is used to analyze by the linear regression method. The results show that: when the spraying system in the synthesized mining face adopts the group spacing of 10 m, the water temperature is 286 K, and the pressure is 6 MPa, the single group peak temperature reaches 1.3 ℃ compared with the conventional ventilation method. After the application in the field, the temperature of most areas on the sidewalk side of the working face was lower than 26 ℃, the maximum temperature dropped to below 27 ℃, the minimum temperature was as low as 24.7 ℃, which effectively realized the regional cool.
