In order to effectively restrain the adverse effects of high temperature environment on the working area of fully mechanized coal mining face, a mathematical model describing the interaction between droplets and air flow was established and the accuracy of the model was verified. Finally, under the same ventilation conditions, the temperature distribution of the nozzle under different temperatures was studied in detail. The results show that the temperature distribution in different areas along the roadway is basically the same when the spray scheme is applied at different temperatures, and all of them decrease first and then increase. In all spray schemes, the best cooling effect is achieved by using K2.0 nozzle and spray water temperature of 278k.
