Numerical Simulation on Thermal Environment of Ventilation for Mine Roadway Heading Face Based on Fluent Software

Based on computational fluid dynamics and the mine ventilation theory,a ventilation turbulence k-ε model of the mine roadway heading face was establis hed and a differential equation to state the turbulence flow of the air flow and the temperature distribution in the mine roadway heading face was derived.With the analy sis on the boundary conditions of the mine heading roadway model,the Fluent software was applied to simulate the thermal and moisture exchange process between th e forced ventilation flow,the surrounding rocks of the mine roadway and the mechanical equipment heat radiation.The TECPLOT software was applied to processing an d the speed vector diagram and the air flow temperature variation under the different ventilation supply value were showed.The simulation calculated results showed th at the ventilation supply value increased could reduce the temperature of the mine roadway.Once the ventilation supply value was too high,the temperature reduction eff ect would not be remarkable steadily.The high temperature status could not be changed only by depending on ventilation.
