Numerical Simulation Study on Optimization of Spray Cooling Mode in High Temperature Operation

Abstract Taking a single mine roadway in a metal mine as the research object, the distribution of wind temperature and wind speed in a single heading is studied by numerical simulation method under the condition of different ventilation in the roadway. The influence rule of different spray angles on the temperature distribution of the roadway is discussed, and the conclusion that the spray angle of the case reaches the optimum cooling effect is 15 degrees. Numerical simulation results show that spray cooling can make up for the defects of traditional pressing ventilation mode and achieve better cooling effect. It should be widely applied in non coal and gas outburst roadway.
